reduce delta cache size to avoid running out of memory on large pack files
As reported by Jerome Kasper, got-index-pack would run out of memory while cloning projects like LLVM or the Linux kernel. The delta cache was pushed to its maximum size limit of ~2GB, which is much higher than the default user data limit on OpenBSD. Set the delta cache size limits to values which should result in the cache limiting itself to 128MB or less.
zero-initialize all of struct got_deflate_buf in got_deflate_init()
Fixes a potential bogus free on error. got_deflate_end() relies on zb.flags to be initialized. It will try to free a bogus zb.outbuf pointer if zb.flags happens to set by uninitialized stack memory while we are calling got_deflate_end() in an error path.

This brings in a build fix for OpenBSD/sparc64.
fix free() of wrong address in gotweb's parse.y
Found by sthen via ports-gcc: gotweb/parse.y:504:3: warning: attempt to free a non-heap object 'file'
remove casts which make older gcc versions unhappy

fix reference counting of raw objects opened via privsep helpers
Such objects were never closed, resulting in memory and file descriptor leaks.
use mkstemps(3) instead of mkstemp(3) for opening named temporary files
Allows 'got commit' to use a ".diff" suffix for temporary diff files. ok op@
