Fixes an issue encountered by mlarkin@ where the auth process was working with an empty list of repositories and kept saying it could not find a repository which was obviously listed in gotd.conf. Now we can see errors from fopen() in the logs instead. Old code was copied from gotwebd where the config file is optional.

and use it to avoid hardcoding the digest type in a few places. ok stsp@

Currently only used to detect and avoid storing duplicate IDs sent in want and have lines by the client. If in the future we ever wanted to check which IDs the client has already sent us we could now do O(1) hash table lookups rather than iterating arrays. ok op@

getline(3) allows to safely re-use the storage. While here rename `size' to `linesize', `len' to `linelen', and properly initialize `linesize' to zero; suggested by tb@ ok tb@

Gap in the documentation pointed out by James Cook.

ed users are reading files with their minds rather then their eyes, and might therefore be missing important visual clues we write into files before the user gets to edit them. Use of vi(1) ensures that such clues will not be missed.

The sending and receiving side are sending the data differently. It works now by chance since a struct got_object_id is "just" a SHA1_DIGEST_LENGTH sized buffer, but will break in the future. Furthermore, the structure of the data as described in got_lib_privsep.h is not respected, as the path_len field is not transmitted. Change it to send/receive a whole struct got_object_id, the path without the NUL and the proper length. (The path is also actually mandatory, so assert it too.) improvements + ok stsp@

both were changed to use the new got_hash APIs.

This adds a set of functions to abstract over SHA1Init, SHA1Update, SHA1Final, their respective SHA256 variants and how to compare digests. Replace all the SHA1*() usage with the new APIs. It's a preparatory step for sha256 handling. ok stsp@

it abstracts over the hash type and ensures that object ids are zero'ed before their sha1 digest is written. Needed by the incoming sha256 support. ok stsp@

It will soon grow functions to deal with sha256 too. stsp@ agrees.
