portable: add libbsd to README This adds libbsd to the README files to indicate a core dependency. Originally from Ashish SHUKLA.

portable: set next version Bump the version in git now to the next version. Over time, this should really use the SHA1 to indicate a non-released build.

Release 0.69

bump version number

CHANGES for 0.69

add -q to "gotadmin pack" usage

got patch: allow to reverse a patch add a flag to got_patch to reverse a patch before applying and the -R flag for `got patch'. 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@

test `got patch' vs path-prefixes, relative paths and strip reminded by and 'looks fine' to stsp@

typos

mention -p in usage_patch

got patch: resolve paths from the current working directory this allow to apply patches from subdirectories of the work tree root. Prodded by naddy@, ok stsp@.

portable: freebsd: portably include sha1 The SHA implementation is found portably across systems, so don't include sha1.h directly.

portable: CI (linux): add libbsd-dev This needs to be explicitly installed.
