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>

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

improve error reporting when delta application fails

make fclose(3) failure checks consistent; check 'fclose() == EOF' everywhere ok millert, naddy

convert tree entries from SIMPLEQ to an array

stop storing decompressed delta data in struct got_delta; fetch it on demand

avoid dependency on delta.o in binaries which don't need it

rename got_error_prefix_errno() to got_error_from_errno()

got_error_from_errno -> got_error_prefix_errno also add got_error_prefix_errno2 and got_error_prefix_errno3 which should hopefully all be merged into a single function with variadic args (but can't alloc mem)

make got path APIs available to library consumers

check for errors from fclose()

remove struct got_object from public library API

check for size_t overflow in got_delta_apply_in_mem() like libgit2's c15771104 (delta: fix overflow when computing limit)

bounds checks before memcpy in got_delta_apply_in_mem()

no need to zero got_delta during allocation
