run the search for deltas to reuse in got-read-pack This significantly speeds up the deltification step of packing by avoiding imsg traffic. gotadmin no longer requests individual raw deltas from got-read-pack to check whether it can reuse them. Instead, got-read-pack obtains a list of objects we want to pack, and hands back the list of all deltas in its pack file which can be reused. Messages are now batched such that imsg buffers are filled as much as possible. Another advantage is that deltas we are not going to reuse will no longer be written to the delta cache file, saving disk space. Before this patch, any raw delta candidate was written to the delta cache file by got-read-pack, and the decision whether to reuse the delta happened afterwards in the gotadmin process. Code for reading individual raw deltas is now unused and could be removed at some point. ok op@

store deltas in compressed form while packing, both in memory and cache file This reduces memory and disk space consumption during packing. with tweaks + memleak on error fix from op@ ok op@

inline struct got_object_id in struct got_object_qid Saves us from doing a malloc/free call for every item on the list. ok op@

ignore the return value of closefrom(2); patch by Anna a.k.a. CyberTailor millert@ suggests that this check is not needed, and that ideally we should be using close-on-exec instead. I will look into this, but in the meantime this change will help -portable: https://bugs.gentoo.org/828003

portable: add FreeBSD support This adds the capability to compile got-portable on FreeBSD.

portable: initial Linux compilation This commit modifies the GoT main branch to be able to compile it under linux.

indentation fixes

provide separate send {} and fetch {} configuration blocks in got.conf Feature requested by naddy. ok naddy, who also suggested some tweaks that will arrive shortly

add 'got send' command for sending changes to remote repositories Known to work against git-daemon and github Git server implementations. Tests by abieber, naddy, jrick, and myself. Man page additions reviewed by Lucas.

don't scan pack index offsets for large values if pack file is < 2GB This saves an iteration over the entire h->offsets array when opening a pack index which should not contain large offsets in the first place. ok millert@

verify object ID checksums while loose objects are being accessed

switch from SIMPLEQ to equivalent STAILQ macros The singly-linked tail queue macros were added to OpenBSD 6.9 and are more widely available on other systems. ok stsp

raw object size should not include the length of the object's header This way, the size of a raw object is the same regardless of whether the object was found in a loose object file or in a pack file.
