Change the API of supporting functions `_load_public_keys()` and
`_ostree_repo_sign_verify()` -- pass repo object and remote name
instead of OtPullData object. This allows to use these functions
not only in pull-related places.

Allow to sign the summary file with alternative signing mechanism.
Added new options:
- --sign-type -- select the engine (defaults to ed25519)
- --sign -- secret key to use for signing

Usage of 'g_warning()' inside keys loading funcrion lead to false
failure: the key loading attempt for the wrong engine breaks the
pulling process instead of trying to use this key with correct engine.

The initial implementation with single key for secret and public parts
doesn't allow to test pulling with several signing engines used.

Option '--keys-dir' is used for redefinition of default directories with
public/revoked keys. If keys directory is set then default directories
are ignored and target directory is expected to contain following
structure for ed25519 signature mechanism:
dir/
trusted.ed25519 <- file with trusted keys
revoked.ed25519 <- file with revoked keys
trusted.ed25519.d/ <- directory with files containing trusted keys
revoked.ed25519.d/ <- directory with files containing revoked keys

API changes:
- added function `ostree_sign_add_pk()` for multiple public keys using.
- `ostree_sign_set_pk()` now substitutes all previously added keys.
- added function `ostree_sign_load_pk()` allowed to load keys from file.
- `ostree_sign_ed25519_load_pk()` able to load the raw keys list from file.
- use base64 encoded public and private ed25519 keys for CLI and keys file.

This builtin allows to sign and verify commit with new signature
mechanism. At the moment it is possible to use 'dummy' and 'ed25519'
signing modules.
'dummy' module use any ASCII string from command line as a key for
commit's signing or verification.
Support of ed25519 signature is implemented with `libsoium` library.
Secret and public key should be provided in hex presentation via
command line.
Based on 'gpg-sign' source.

Added the initial version of signing interface allowing to allowing to
sign and verify commits.
Implemented initial signing modules:
- dummy -- simple module allowing to sign/verify with ASCII string
- ed25519 -- module allowing to sign/verify commit with ed25519
(EdDSA) signature scheme provided by libsodium library.

The [dev-overlay](332c6ab3b9/src/cmd-dev-overlay)
script shipped in coreos-assembler mostly exists to deal
with the nontrivial logic around SELinux policy. Let's make
the use case of "commit some binaries overlaying a base tree, using
the base's selinux policy" just require a magical
`--selinux-policy-from-base` argument to `ostree commit`.
A new C API was added to implement this in the case of `--tree=ref`;
when the base directory is already checked out, we can just reuse
the existing logic that `--selinux-policy` was using.
Requires: https://github.com/ostreedev/ostree/pull/2039
Rework the simple cases of "commit ." and "commit argv[1]" to
generate the more general "--tree=X --tree=Y" path, so that we
only have one primary control flow here.
Prep for a future patch around loading SELinux policy from
the first argument.
