Use git index-pack for much better fetch and clone
Fix locale handling so that gpg and git use the user locale
Use `xgrep` function to always exit grep with success
Fix bug in do_fetch, skip empty line
Fix bugs with gitception://<giturl> related to concurrency with git

Make sure we do not overwrite FETCH_HEAD. Using stacked gitception://
URLs was useful to make sure we handle our temporaries in a safe way.
Cleanup manifest verification, require a non-empty manifest
Disable keyring when using symmetric crypto
Use git config gcrypt.keyring for repository security

To verify signatures, we need a small keyring where the user has
selected just the keys who are allowed to access and update the
repository.
Require signed masterkey (REPO FORMAT CHANGE)
README, describe new option gcrypt.keyring
Fix retval of gitception_get
Write gitception_get in a simpler way
Use gpg --with-colons --print-md
Use gpg --secret-keyring /dev/null where possible
Provide clear messages for signing and verifying
When decrypting or verifying the master key, check input type

We rely on gpg to exit with success, but we also check the status output
to verify that the expected action (decrypt with privkey or verify) was
performed.
