The funcs xbps_pkg_name() and xbps_pkgpattern_name() were
using malloc(3) to return the result, until now.
They now have been changed to not allocate the result
via malloc, the caller is responsible to provide a buffer
at least of XBPS_NAME_SIZE (64).
If for whatever reason the pkgname can't be guessed,
returns false. This should avoid lots of small allocs
around libxbps.
New functions have the following prototype:
bool xbps_pkg_name(char *dst, size_t len, const char *pkg)
bool xbps_pkgpattern_name(char *dst, size_t len, const char *pkg)
as suggested by @duncaen.
