Filesystem::readRandomCharacters()
Summary: See T547. To improve auditability of use of crypto-sensitive hash
functions, use Filesystem::readRandomCharacters() in place of
sha1(Filesystem::readRandomBytes()) when we're just generating random ASCII
strings.
Test Plan:
- Generated a new PHID.
- Logged out and logged back in (to test sessions).
