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