check the maximum cached delta size against the correct constant

convert delta cache to a hash table This approach uses more memory but is much faster. To offset the additional memory usage somewhat the cache now stores very small deltas only. However, overall memory usage goes up. Hopefully we will find a way to reduce this later. ok op@

set `ret' in a few places where it was forgotten; ok tracey@

don't pass $ret to test_done on failure when it's known to be zero Otherwise the test directory it's not left in place; ok tracey@

properly swap cached struct pack array elements in got_repo_cache_pack() Avoids clobbering open files for delta base/accumulation, leaking file descriptors, and triggering errors from close(2) during got_repo_close() as we try to close the same file descriptor more than once.

move creation of tempfiles outside of lib/diff.c ok tracey

tog: override SIGTERM and SIGINT handlers to avoid ncurses cleanup() handler ok thomas

reduce GOT_PACK_CACHE_SIZE to 32, otherwise it uses too many open files found by tracey

ensure that all open basefd/accumfd get closed in got_repo_close() found by tracey

open temporary files needed for delta application in got_repo_open() This prepares for callers of got_repo_open() that cannot afford to open files in /tmp, such as gotwebd. In a follow-up change, we could ask such callers to pass in the required amount of open temporary files. One consequence is that got_repo_open() now requires the "cpath" pledge promise. Add the "cpath" promise to affected callers and remove it once the repository has been opened. ok tracey
