use the commitid in the patch diff3 conflict header suggested by and ok stsp@

got patch: use diff3 to merge the changes Parse the "blob -" metadata in diffs produced by 'got diff' and use the original file for patching. Then, use the diff3 with the current version of the file to merge the differences. This solves many failures automagically or at least turns them into a conflict. ok/improvements stsp@

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: switch from fseek() to fseeko(), use unary minus while here ok op

got patch: fail when reading empty hunks

got-read-patch: rename `ok' variable and simplify the parsing a bit

trailing whitespaces

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@

fgetc() returns int, not char; fixes -Werror build on armv7

got patch: handle "\ No newline at end of file"

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: 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.
