system/yaml: Backport emitter fix from v0.2.2-pre1

These patches fix an emitter problem that prevents PyYAML 3.13's test
suite from passing. They should not be necessary when libyaml v0.2.2 is
released.

user/keychain: new package

Keychain is a set of shell scripts (edited by a Perl script) that automates the handling of OpenSSH, OpenPGP, and other security keys.

Given that it's a shell script, I did not include dependencies on OpenSSH or GnuPG since it can be used with one, the other, both, or one of the more exotic options. Its behavior is completely dependent on the user telling it what to use.
