remove trailing whitespace; patch by Josiah Frentsos

parse tree entries into an array instead of a pathlist Avoids some extra malloc/free in a performance-critical path. 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@

fix loose object file header parser for zero-length headers ok millert tracey

map raw object files into memory while packing if possible

raw object blocksize and read buffer were unused; remove them

cache raw objects in order to speed up gotadmin pack

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

match the unsigned char type used by the zlib interface ok stsp

use less memory allocations when formatting log messages Rewrite got_object_commit_get_logmsg() such that only one memory allocation is made when creating a pretty version of a log message. ok naddy@

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

add a user data pointer to struct got_object_qid This will be required by a future 'gotadmin pack' command.

tolerate tag objects which lack tagger timestamp information Fixes interop with repos such as git://github.com/steveicarus/iverilog.git Found by + ok naddy

fix parsing of tag objects which lack a tag message This problem could be triggered with the u-boot repository: $ git clone --bare https://gitlab.denx.de/u-boot/u-boot.git $ got log -r u-boot.git got-read-pack: bad object data got: bad object data $

use size_t for loop indices to avoid signedness warnings; from emaste@freebsd
