[oe] [RFC, PATCH] Add minver/maxver to patch.bbclass, update bluez

[Tom Rini]

Hey all,

In digging at some other bluez problems, I found that at least
4.91 no longer needs the sbc-thumb patch.  But without moving it to the
N versions of bluez4 we have or starting a new inc file for later bluez4
versions, there wasn't a clean way to exclude the patch.  Until now.
Borrowing the minrev/maxrev logic I added minver/maxver patch params
and tested them lightly (the patch is applied on 4.89 and not on
4.91).  I'm cc'ing Koen here because patch #3 adds 4.91 and make it
default for Angstrom, but all I've done myself is build testing.
It should be safe, based on upstream changelog tho.
