plug some fd leaks in the fdopen{,dir} error paths There's also a memory leak fixed. ok stsp@

use INT32_MAX rather than INT_MAX for GOT_FILEIDX_MAX_ENTRIES it's a different way to spell the same number, but it's more evocative since the on-disk format is 32 bits wide. ok stsp

speed up read_fileindex_path() Use a local buffer instead of calling reallocarray() every 8 bytes; the speed up is measurable. The downside is that we're now limited to paths long at most PATH_MAX bytes, but since this is the fileindex it's not an issue in practice. ok jamsek stsp

use a separate .cvg meta data directory for cvg(1) work trees This prevents mixing the use of got and cvg clients in the same work tree. Avoids confusion going forward while cvg differentiates itself further. tog(1) and gotadmin(1) remain compatible with both work tree formats. These tools only read work trees to locate the corresponding repository.

free fileindex entry upon add_entry() failure Very unlikely (an occurrence of it would mean that got produced an invalid fileindex) and harmless anyway since we would just terminate, but a leak is still a leak. ok stsp@

support histedit fold operations which delete a file and then add it again problem found by naddy@ ok op@

portable: configure: split out dependencies Rather than assume all dependencies are required for all programs, split them out. This will make packaging easier, as well as splitting the code to use subprojects. Note that due to the use of config.h semantics, in most cases the got_compat.h header file is now at the top of the .c file it is included in, so that it can handle the system header inclusion properly.

add some helper functions to compute hashes This adds a set of functions to abstract over SHA1Init, SHA1Update, SHA1Final, their respective SHA256 variants and how to compare digests. Replace all the SHA1*() usage with the new APIs. It's a preparatory step for sha256 handling. ok stsp@

portable: remove endian.h This is included portably.

portable: rework SHA detection Simply the SHA detection by not predicating on libcrypto, but instead checking individual header files.

portable: remove sha1.h; found portably Remove sha1.h as this is found portably across systems.

include sha2.h too where sha1.h is included In preparation for wide sha256 support; stsp@ agrees. Change done mechanically with find . -iname \*.[cy] -exec sam {} + X ,x/<sha1\.h>/i/\n#include <sha2.h>

got: minor refactor of got_pathlist_free() API Accept flag parameter to optionally specify which pointers to free. This saves callers looping through the list to free pointers. ok + fix stsp@

remove trailing whitespace; patch by Josiah Frentsos

portable: add back sys/queue.h Now that the handling of including sys/queue.h is better, there's no need to remove those lines from the source. Copy the location of those original sys/queue.h lines from upstream at the same line number, so as to avoid any conflicts in the future.

portable: make UUID includes generic Move the detection of UUID header files to be included portably. This will have no functional effect until MacOS detection is put in place.

do not skip ignored directories in 'got status' if they contain tracked files Fixes regression introduced by commit 41f061b2f459318f3738f59d7676efccc4beb344 where tracked files inside an ignored directory were reported as missing.
