Changes from RFC v1:
Patch 1: Several typos / grammatical errors (thanks Eric, John)
Make id_subsys_str[] const pointer to const strings (thanks Eric)
Moved id_subsys_str[] out from id_generate() (thanks John)
Assert on null string for given id (thanks Eric)
Zero-pad the 2-digit random # (thanks John)
Patch 2: None
Born from the conversation on qemu-devel, this generation scheme uses the
format ultimately proposed by Kevin, after list discussion.
It attempts to keep the ID strings as small as possible, while fulfilling:
1.) Guarantee no collisions with a user-specified ID
2.) Identify the sub-system the ID belongs to
3.) Guarantee of uniqueness
4.) Spoiling predictibility, to avoid creating an assumption
of object ordering and parsing (i.e., we don't want users to think
they can guess the next ID based on prior behavior).
See patch 1 for the generation scheme details.
