gap-cvec-2.5.7-bp151.2.11

- Update to new upstream release 2.5.7
  * Remove CompatibleMatrix method (this *undocumented* API will be
    removed in GAP 4.9).
  * Fix several broken references in the manual.

- Update to new upstream release 2.5.6
  * Fixed a bug which resulted in cvec incorrectly
  converting certain GAP matrices to cvec matrices.

- Update to new upstream release 2.5.5
  * Some functions accept slightly more general input. For example,
  it is now in some cases acceptable to use finite field elements
  like Z(4)^0 (which is equal, but not identical, to Z(2)^0) as
  input when cvec is expecting elements of GF(2).
  * Fix EmptySemiEchelonBasis: its documentation said it expects a
  sample vector, but the implementation expected a sample matrix.
  Now both are possible, and both are documented.

- Update to new upstream release 2.5.3
  * Remove some leftover GAP 4.4 compatibility code

- Update to new upstream release 2.5.1
  * Add methods for \^ for cvecs and Frobenius automorphisms
  * Add methods for \^ for cmats and Frobenius automorphisms
  * Fix a bug in unpickling semi echelonised bases
  * Update and tweak the package build system

- Split cvec (version 2.4) off the gap RPM package
