so we have buffer space for the ".part" suffix.

fix return value for usage text

fix digest to be unsigned char buffer

Try all patches and return of list of patches that failed rather than
exit on first failed patch.

But let env var CFLAG override

Without these we don't have any optimizations by default in D applications

Store exit code in the variable 'e', then return it, if there are no
errors then it will return 0 as that is the default value, otherwise it
will return 1 and error out as previously

use whitespace instead of tab where appropriate

Root cause of a malloc() failure when processing large files (>2GB) in an archive.

That ensures that we always use the versions specified in the Cargo.lock
file, which is required for reproducible builds

This is required for proper debug info for D packages

This commit broke abuild-rmtemp which has a prefix check to ensure it
doesn't remove non-abuild directories. Revert the commit instead of
adjusting the prefix check for now.

This reverts commit d0828c06.

From `go help environment`:

	GOFLAGS
		A space-separated list of -flag=value settings to apply
		to go commands by default, when the given flag is known by
		the current command. Flags listed on the command-line
		are applied after this list and therefore override it.

And from `go help build`:

	-buildmode mode
		build mode to use. See 'go help buildmode' for more.

Setting this environment variable in /etc/abuild.conf allows us to build
all go binaries on the builders as PIE without needing to patch the go
compiler itself.

fixes commit 012a1793

This allows using default_prepare to apply compressed patches,
e.g. the linux-lts kernel patches (compressed using XZ).

With the None build type used nowadays these should be picked up
automatically by the environment. If not, we would also need to pass
CPPFLAGS and LDFLAGS explicitly.

fix issue with how perl-dev was added as a makedepends
perl probably should be a dependency of all per modules

aports convention is to delete empty variables from APKBUILD files
this causes and issue with updating existing APKBUILD files
new depends, makedepends or checkdepends are added to process the file
properly.  Empty variables are then deleted once the file processes correctly

remove trailing pkgver from some module names
attempt to use additional variable content to determine perl package name
this now appears to support all but 10 or 11 non metacpan api retrievable
 module information and add a package mapping for perl-ldap

do_depends can send multiple meta dependencies as additional parameters
parse_deps was not itterating through each of the parameters
this fix gets the entire list without duplicate entries
