ensure that obj/parse.h gets removed during 'make clean'

fix gotd sometimes reading reused deltas from wrong pack file The reuse-pack is pinned but may change its cache slot while objects are being deltified. Refresh the pointer to the pinned reuse-pack before writing out the pack file, ensuring that reused deltas will in fact be read from the reuse-pack and not some other pack. Otherwise gotd may send a broken pack file, or hit an ERR_RANGE condition if the pack file which now occupies the pinned-pack's old cache slot is shorter. Which can trigger attempts to read beyond end-of-file which show up in the logs like this: gotd[37311]: repo_read /var/git/got.git: sending packfile: value out of range gotd[43877]: uid 1002: value out of range gotd[43877]: uid 1002: disconnecting

add xfail test for histedit folding of delete followed by add If a file is deleted, then in modified form added again, folding should restore the file with its new contents. ok stsp

regress: replace "sed -i" with ed(1) for portable in-place editing "sed -i" is fundamentally unportable. GNU and OpenBSD sed(1) treat the extension for the backup file as an optional argument and use "sed -i" for no backup file. FreeBSD sed(1) treats the extension as an obligatory argument and uses "sed -i ''" for no backup file. There is no single syntax that works for both. ok stsp op

regress/commit.sh: tweak editor.sh for test_commit_prepared_logmsg no need for sed (which doesn't change anything anyway), a no-op editor script is enough; the test ensures that the prepared log message is used. ok naddy@ stsp@

gotd requires a config file; don't fail silently when gotd.conf cannot be read Fixes an issue encountered by mlarkin@ where the auth process was working with an empty list of repositories and kept saying it could not find a repository which was obviously listed in gotd.conf. Now we can see errors from fopen() in the logs instead. Old code was copied from gotwebd where the config file is optional.

add got_repo_get_object_format() and use it to avoid hardcoding the digest type in a few places. ok stsp@
