Adjust to OpenSSL 3+, which deprecates its SHA-1 functions based on
its traditional API, by using its EVP API instead.
* ew/hash-with-openssl-evp:
avoid SHA-1 functions deprecated in OpenSSL 3+
sha256: avoid functions deprecated in OpenSSL 3+
OpenSSL 3+ deprecates the SHA1_Init, SHA1_Update, and SHA1_Final
functions, leading to errors when building with `DEVELOPER=1'.
Use the newer EVP_* API with OpenSSL 3+ (only) despite being more
error-prone and less efficient due to heap allocations.

oidhash() was used by both hashmap and khash, which makes sense.
However, the location of this function in hashmap.[ch] meant that
khash.h had to depend upon hashmap.h, making people unfamiliar with
khash think that it was built upon hashmap. (Or at least, I personally
was confused for a while about this in the past.)
Move this function to hash-ll, so that khash.h can stop depending upon
hashmap.h.
This has another benefit as well: it allows us to remove hashmap.h's
dependency on hash-ll.h. While some callers of hashmap.h were making
use of oidhash, most were not, so this change provides another way to
reduce the number of includes.

hash.h depends upon and includes repository.h, due to the definition and
use of the_hash_algo (defined as the_repository->hash_algo). However,
most headers trying to include hash.h are only interested in the layout
of the structs like object_id. Move the parts of hash.h that do not
depend upon repository.h into a new file hash-ll.h (the "low level"
parts of hash.h), and adjust other files to use this new header where
the convenience inline functions aren't needed.
This allows hash.h and object.h to be fairly small, minimal headers. It
also exposes a lot of hidden dependencies on both path.h (which was
brought in by repository.h) and repository.h (which was previously
implicitly brought in by object.h), so also adjust other files to be
more explicit about what they depend upon.
