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@

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@

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>

add functions to extract object ids from fileindex entries ok stsp
