mpfr-4.2.1-160000.2.2

- Update to mpfr 4.2.1
  * Includes all fixes from mpfr-4.2.0-cummulative.patch which is
    subsequently removed.
  * Improved MPFR manual.
  * Configure tests: replaced the test of the link with GMP, in order
    to avoid the use of a function without a prototype (Autoconf issue), as
    this is obsolescent in ISO C. The new test should be more robust.

- Update mpfr-4.2.0-cummulative.patch, adds patches fixing the following bugs
  * the mpfr_reldiff function, which computes |b-c|/b, is buggy on special
    values, e.g. on the following (b,c) values: (+Inf,+Inf) gives ±0
    instead of NaN (like NaN/Inf); (+0,+0) gives 1 instead of NaN (like 0/0);
    (+0,1) gives 1 instead of Inf (like 1/0). Moreover, the sign of 0 for
    (+Inf,+Inf) or (-Inf,-Inf) is not set, i.e. it is just the sign of the
    destination before the call; as a consequence, results are not even
    consistent.
  * the reuse tests are incomplete: the sign of a result zero is not checked,
    so that it can miss bugs (one of the mpfr_reldiff bugs mentioned above,
    in particular).
  * the general code for the power function (mpfr_pow_general internal
    function) has two bugs in particular cases: the first one is an incorrect
    computation of the error bound when there has been an intermediate
    underflow or overflow (in such a case, the computation is performed
    again with a rescaling, thus with an additional error term, but there is
    a bug in the computation of this term), so that the result may be
    rounded incorrectly (in particular, a spurious overflow is possible);
    the second one occurs in a corner case (destination precision 1,
    rounding to nearest, and where the rounded result assuming an unbounded
    exponent range would be 2emin-2 and the exact result is larger than this
    value), with the only consequence being a missing underflow exception
    (the underflow flag is not set).
  * the mpfr_compound_si function can take a huge amount of memory and time
    in some cases (when the argument x is a large even integer and xn is
    represented exactly in the target precision) and does not correctly
    detect overflows and underflows
  * MPFR can crash when a formatted output function is called with
    %.2147483648Rg in the format string.

- Add mpfr-4.2.0-cummulative.patch, cummulative patches for
  mpfr 4.2.0:
  * A test of the thousands separator in tsprintf.c is based on the
    output from the GNU C Library up to 2.36, which is incorrect.
  * The mpfr_ui_pow_ui function has infinite loop in case of overflow.
  * The tfprintf and tprintf tests may fail in locales where decimal_point
    has several bytes, such as ps_AF.
  * In particular cases that are very hard to round, mpfr_rec_sqrt may yield
    a stack overflow due to many small allocations in the stack, based on
    alloca().
- Remove tests-tsprintf.patch that's included in the above set.

- tests-tsprintf.patch: Avoid testsuite failure with glibc >= 2.37

- Update to mpfr 4.2.0
  * New functions mpfr_cosu, mpfr_sinu, mpfr_tanu, mpfr_acosu, mpfr_asinu,
    mpfr_atanu and mpfr_atan2u.
  * New functions mpfr_cospi, mpfr_sinpi, mpfr_tanpi, mpfr_acospi, mpfr_asinpi,
    mpfr_atanpi and mpfr_atan2pi.
  * New functions mpfr_log2p1, mpfr_log10p1, mpfr_exp2m1, mpfr_exp10m1 and
    mpfr_compound_si.
  * New functions mpfr_fmod_ui, mpfr_powr, mpfr_pown, mpfr_pow_uj, mpfr_pow_sj
    and mpfr_rootn_si (mpfr_pown is actually a macro defined as an alias for
    mpfr_pow_sj).
  * Bug fixes.
    In particular, for the formatted output functions (mpfr_printf, etc.),
    the case where the precision consists only of a period has been fixed
    to be like ".0" as specified in the ISO C standard, and the manual has
    been corrected and clarified.
    The macros of the custom interface have also been fixed: they now behave
    like functions (except a minor limitation for mpfr_custom_init_set).
- Remove mpfr-4.1.1-patch01.patch which is included in the new release.

- Add mpfr-4.1.1-patch01.patch to fix bug with code using
  the mpfr_custom_get_kind macro.

- package license files correctly

- Update to mpfr 4.1.1
  * Bug fixes (see <https://www.mpfr.org/mpfr-4.1.0/#fixed> and/or the
    ChangeLog file), in particular for macros implementing functions.
  * Improved manual formatting.
  * Accumulated bugfixes
- Remove mpfr-4.1.0-p7.diff, all patches are contained in the
  new version.
- Update mpfr.keyring

- Add cummulative patch mpfr-4.1.0-p7.diff fixing various bugs.

- Update to mpfr 4.1.0
  * New function mpfr_get_str_ndigits about conversion to a string of digits.
  * New function mpfr_dot for the dot product (incomplete, experimental).
  * New functions mpfr_get_decimal128 and mpfr_set_decimal128 (available only
    when MPFR has been built with decimal float support).
  * New function mpfr_cmpabs_ui.
  * New function mpfr_total_order_p for the IEEE 754 totalOrder predicate.
  * The mpfr_out_str function now accepts bases from -2 to -36, in order to
    follow mpfr_get_str and GMP's mpf_out_str functions (these cases gave an
    assertion failure, as with other invalid bases).
  * Shared caches: cleanup; really detect lock failures (abort in this case).
  * The behavior of the formatted output functions (mpfr_printf, etc.) with
    an empty precision field has improved: trailing zeros are kept in a way
    similar to the formatted output functions from C.
  * Improved mpfr_add and mpfr_sub when all operands have a precision equal to
    twice the number of bits per word, e.g., 128 bits on a 64-bit platform.
  * Optimized the tuning parameters for various architectures.
  * Improved test coverage to 98.6% of code for x86_64.
  * Bug fixes.
  * MPFR manual: corrected/completed the mpfr_get_str description in order to
    follow the historical behavior and GMP's mpf_get_str function.
- Remove mpfr-4.0.2-p6.patch and floating-point-format-no-lto.patch
