pcre2-10.32-2.1

- pcre2 10.32:
  * pcre2grep now supports the inclusion of binary zeros in
    patterns that are read from files via the -f option.
  * In pcre2_dfa_match(), internal recursive calls no longer use
    the stack for local workspace and local ovectors
  * Updated to Unicode version 11.0.0.
  * (*ACCEPT:ARG), (*FAIL:ARG), and (*COMMIT:ARG) are now supported.
  * Add support for \N{U+dddd}, but only in Unicode mode.
  * Addesupport for (?^) to unset all imnsx options

- Drop conditions for old distributions
- Do profile guided build

- Update to new upstream release 10.31
  * New pcre2_config() options: PCRE2_CONFIG_NEVER_BACKSLASH_C and
    PCRE2_CONFIG_COMPILED_WIDTHS.
  * New pcre2_pattern_info() option PCRE2_INFO_EXTRAOPTIONS to
    retrieve the extra compile time options.
  * Public names for all pcre2_compile() error numbers.
  * Added PCRE2_CALLOUT_STARTMATCH and PCRE2_CALLOUT_BACKTRACK
    bits to a new field callout_flags in callout blocks.
- use https for main site
- cleanup with spec-cleaner

- Update to new upstream release 10.30
  * The main interpreter, pcre2_match(), has been refactored into
    a new version that does not use recursive function calls for
    remembering backtracking positions. The new implementation
    allows backtracking into recursive group calls in patterns,
    making it more compatible with Perl. For patterns that have a
    lot of backtracking, the heap is now used, and there is
    explicit limit on the amount, settable by
    pcre2_set_heap_limit(). The "recursion limit" is retained,
    but is renamed as "depth limit".
  * The new option PCRE2_ENDANCHORED insists that a pattern match
    must end at the end of the subject.
  * The new option PCRE2_EXTENDED_MORE implements Perl's /xx
    feature, and pcre2test is upgraded to support it. Setting
    within the pattern by (?xx) is Also supported.
  * (?n) can be used to set PCRE2_NO_AUTO_CAPTURE, because Perl
    now has this.
  * Additional pattern compile options in the compile context are
    now available: PCRE2_EXTRA_ALLOW_SURROGATE_ESCAPES and
    PCRE2_EXTRA_BAD_ESCAPE_IS LITERAL.
  * The newline type PCRE2_NEWLINE_NUL is now available.
  * The match limit value now also applies to pcre2_dfa_match()
    as there are patterns that can use up a lot of resources
    without necessarily recursing very deeply.
  * Various minor security fixes found by fuzzers:
    + bsc#1037165: crash for forward reference in lookbehind with
    PCRE2_ANCHORED
    + CVE-2017-8786: heap-based buffer overflow write in pcre2test
    (bsc#1036942)
    + CVE-2017-7186: DoS by triggering an invalid Unicode property
    lookup (bsc#1030066)
- Switch source URLs to use HTTP.

- fix SLE 11 build

- pcre2grep can now read .gz and .bz2 files directly
- pcre2test is now built to support line editing

- pcre2 10.23:
  * major re-factoring of the pcre2_compile.c file
  * Back references are now permitted in lookbehind assertions when
    there are no duplicated group numbers (that is, (?| has not
    been used), and, if the reference is by name, there is only one
    group of that name. The referenced group must, of course be of
    fixed length.
  * \g{+<number>} (e.g. \g{+2} ) is now supported. It is a "forward
    back reference" and can be useful in repetitions
    (compare \g{-<number>} ). Perl does not recognize this syntax.
  * pcre2grep now automatically expands its buffer up to a maximum
    set by --max-buffer-size.
  * The -t option (grand total) has been added to pcre2grep.
  * A new function called pcre2_code_copy_with_tables() exists to
    copy a compiled pattern along with a private copy of the
    character tables that is uses.

- Explicitly package %{_docdir}/%{name} to fix build with RPM 4.13.

- pcre2 10.22:
  * The POSIX wrapper function regcomp() did not used to
    support back references and subroutine calls if called with the
    REG_NOSUB option. It now does.
  * A new function, pcre2_code_copy(), is added, to make a copy of a
    compiled pattern.
  * Support for string callouts is added to pcre2grep.
  * Added the PCRE2_NO_JIT option to pcre2_match().
  * The pcre2_get_error_message() function now returns with a
    negative error code if the error number it is given is unknown.
  * Several updates have been made to pcre2test and test scripts
  * Fix CVE-2016-3191: workspace overflow for (*ACCEPT) with deeply
    nested parentheses (boo#971741)

- Update to new upstream release 10.21
  * Improve JIT matching speed of patterns starting with + or *.
  * Use memchr() to find the first character in an unanchored match
  in 8-bit mode in the interpreter. This gives a significant speed
  improvement.
  * 10.20 broke the handling of [[:>:]] and [[:<:]] in that
  processing them could involve a buffer overflow if the
  following character was an opening parenthesis.
  * 10.20 also introduced a bug in processing this pattern:
  /((?x)(*:0))#(?'/, which was fixed.
  * A callout with a string argument containing an opening square
  bracket, for example /(?C$[$)(?<]/, was incorrectly processed and
  could provoke a buffer overflow.
  * A possessively repeated conditional group that could match an empty
  string, for example, /(?(R))*+/, was incorrectly compiled.
  * The Unicode tables have been updated to Unicode 8.0.0.
  * An empty comment (?#) in a pattern was incorrectly processed and
  could provoke a buffer overflow.
  * Fix infinite recursion in the JIT compiler when certain patterns
  /such as (?:|a|){100}x/ are analysed.
  * Some patterns with character classes involving [: and \\ were
  incorrectly compiled and could cause reading from uninitialized
  memory or an incorrect error diagnosis. Examples are:
  /[[:\\](?<[::]/ and /[[:\\](?'abc')[a:].
  * A missing closing parenthesis for a callout with a string argument
  was not being diagnosed, possibly leading to a buffer overflow.
  * If (?R was followed by - or + incorrect behaviour happened instead
  of a diagnostic.
  * Fixed an issue when \p{Any} inside an xclass did not read the current
  character.
  * About 80 more fixes, which you can read about in the ChangeLog
  shipped with the libpcre2-8-0 package.

- PCRE2 10.20:
  * Callouts with string arguments and the
    pcre2_callout_enumerate() function have been implemented.
  * The PCRE2_NEVER_BACKSLASH_C option, which locks out the use of
    \C, is added.
  * The PCRE2_ALT_CIRCUMFLEX option lets ^ match after a newline at
    the end of a subject in multiline mode.
  * The way named subpatterns are handled has been refactored. The
    previous approach had several bugs.
  * The handling of \c in EBCDIC environments has been changed to
    conform to the perlebcdic document. (Incompatible change)
  * Bugs have been mended, many of them discovered by fuzzers.

- PCRE2, a re-working of the original PCRE library to provide an
  entirely new API, version 10.10. Not source compatible.
- copy of the pcre package, with the following adjustments:
  * required name changes
  * adjust pcre-8.21-multilib.patch to pcre2-10.10-multilib.patch
  * drop upstreamed pcre-8.32-visibility.patch
  * --enable-{utf8,unicode-properties} became --enable-unicode
  * drop cpp subpackage
  * make test -> check
  * enable 32 bit character support

- pcre 8.37:
  * CVE-2015-2325: Patterns with certain groups specifying a zero
    minimum quantifier caused incorrect code to be compiled,
    leading to an incorrect memory read. [boo#924960]
  * CVE-2015-2326: Specific patterns containing a forward reference
    with subroutine calls caused incorrect code to be compiled
    [boo#924961]
  * CVE-2014-8964: If an assertion condition was quantified with a
    minimum of zero, SIGSEGV or other misbehaviour could occur.
    [boo#906574]
  * further bug fixes as listed in ChangeLog

- Update to version 3.16
  * This is primarily a bug-fix release.
  * The Unicode data tables have been updated to Unicode 7.0.0.
- Remove pcre-commit1472.patch; fixed on upstream release
- Remove obsolete "Obsoletes" tag

- Improve on RPM group classification
- Remove defunct %gpg_verify (replaced by source validators),
  defunct freecode link

- Harden build with full RELRO as this libraries end linked
  to at least one setuid root executable.

- Enable JIT on ppc64le as well

- update to 0.35:
  There have been performance improvements for classes containing non-ASCII
  characters and the "auto-possessification" feature has been extended. Other
  minor improvements have been implemented and bugs fixed. There is a new callout
  feature to enable applications to do detailed stack checks at compile time, to
  avoid running out of stack for deeply nested parentheses. The JIT compiler has
  been extended with experimental support for ARM-64, MIPS-64, and PPC-LE.
- add pcre-commit1472.patch from SVN to work with gcc49, see
  http://bugs.exim.org/show_bug.cgi?id=1463

- Add automake and autoconf as explicit deps as we run autoreconf
