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.
This fixes issues where if xbps-create creates a new archive on a full
disk, it will write an incomplete archive and then later fails to be
read by xbps-rindex.

A segfault in xbps-create(1) was found in:
https://github.com/void-linux/void-packages/pull/7524
xbps-create adds a file type string to the xentry for every file it
finds in `destdir`, files other than symlinks, regular files and
directories weren't handled and resulted in a segfault later when
when processing the xentry structures.
This commit adds checks for sockets and fifos and exits with an
appropriate error message or with a generic error message for every
other unhandled file.
Closes#66
This is the first commit in a series to make xbps-create build
reproducable packages.
xbps-create uses nftw(3) to walk through all files. As nftw doesn't
sort files it may happen that the resulting packages will have
different checksums due to differentiating orders of files on
different filesystems.
To solve this issue xbps-create uses xbps_directory_t, which is always
sorted, instead of a simple linked list.
The latter could be too expensive, and we only care for the data to be written
to the binary package because a bit later we rename() the temporary file,
which will ensure a data flush to disk.
There's no reason to make them absolute, simply store in the metadata
the target file as is. This vastly simplifies the code and makes all
test pass correctly.
