fabec2c5c3 (builtin/receive-pack: switch to use the_hash_algo, 2019-08-18)
renames hmac_sha1 to hmac, as it was updated to use the hash function used
by git (which won't be sha1 in the future).
hmac() is provided by NetBSD >= 8 libc and therefore conflicts as shown by :
builtin/receive-pack.c:421:13: error: conflicting types for 'hmac'
static void hmac(unsigned char *out,
^~~~
In file included from ./git-compat-util.h:172:0,
from ./builtin.h:4,
from builtin/receive-pack.c:1:
/usr/include/stdlib.h:305:10: note: previous declaration of 'hmac' was here
ssize_t hmac(const char *, const void *, size_t, const void *, size_t, void *,
^~~~
Rename it again to hmac_hash to reflect it will use the git's defined hash
function and avoid the conflict, while at it update a comment to better
describe the HMAC function that was used.
