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@

stop relying on commit cache for good performance of got_object_id_by_path() Instead of internally opening and closing the same commit object over and over again, require callers to pass an open commit object in. Avoids an inherent dependency on the commit object cache for reasonable performance. ok op@

reuse existing deltas when creating pack files tested by thomas, naddy, and myself

map raw object files into memory while packing if possible

avoid the creation of new temporary files whenever a packed object is read This speeds up the creation of pack files by about 30%.

add O_CLOEXEC (close-on-exec) flag to open(2) calls suggested by millert ok thomas_adam

raw object blocksize and read buffer were unused; remove them

remove unused internal raw object API functions

cache raw objects in order to speed up gotadmin pack

reuse temporary files which were not used by got_object_raw_open()

add missing error checks in got_object_raw_open()

use RB_TREE instead of STAILQ to manage packindex bloom filters; much faster

implement 'got diff -c' for diffing commits with optional filtering by path Need for filtering by path sugggested by kn@ ok naddy@

verify object ID checksums while loose objects are being accessed

make got_packidx_get_packfile_path() usable for callers who only have a path

implement 'gotadmin cleanup'

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.

introduce got_object_id_queue_copy() This will be required by a future 'gotadmin pack' command.

introduce got_object_open_loose_fd() for library-internal use

add got_packidx_get_packfile_path() for library-internal use

fix open file descriptor leak in error path of read_object_header_privsep()

implement raw object data access; this will be required for packing

make close(2) failure checks consistent; check 'close() == -1' everywhere ok millert, naddy

make fclose(3) failure checks consistent; check 'fclose() == EOF' everywhere ok millert, naddy
