got patch: use ints for line offsets instead of longs
ints have the advantage that their size is more likely to be the same across the various architecture supported by OpenBSD, thus introducing less possible differences. INT_MAX is still (at least) a few order of magnitudes higher than the patches we dealt with (even abnormal ones.) suggested by stsp@
got patch: handle git-style rename diffs
extend the support for git-style diffs to include the "pure rename" case, i.e. when a file is renamed without any edits. ok stsp@
got-read-patch: preserve all \ lines
as a cheap optimization got-read-patch was sending only the "\ No newline at end of file" lines that follows an addition (a "+" line). To be able to reverse patches in the future got_patch needs to know about all of these lines instead. No functional changes intended. ok stsp@
got patch: allow to strip path components
Move some bits from the libexec helper to the main process so we know if the patch was generated by git or not and finally document the automatic stripping of a/ and b/ prefixes added by git-diff(1). ok stsp@
got patch: prefer new name if not /dev/null and not a git-style diff
This fixes a common issue when for e.g. generating patches with $ diff -u foo.orig foo where 'got patch' failed because 'foo.orig' has an 'unexpected status'. prodded by naddy, ok stsp
portable: got-read-patch: use compat includes
Remove the global header #includes for those items which are detected portably.
portable: add landlock to got-patch
Add the appropriate call to tje got-patch machinary to enable landlock();
portable: enable got-read-patch
Allow the libexec helper, `got-read-patch` to be compiled, portably.
