Log:
I'm sure this is wrong... but it's my start. i/o layering. Lots of stuff
disabled/still to be implemented. This served up a few static requests.

+Changes with MPM
+
+* I/O layering and BUFF revamp. See docs/buff.txt. [Dean Gaudet]
+
+* Basic restructuring to introduce the MPM concept; includes various
+ changes to the module API... better described by
+ docs/initial_blurb.txt. [Dean Gaudet]
1.1 apache-2.0/mpm/src/docs/buff.txt
Index: buff.txt
===
- ap_bungetc added
- ap_blookc changed to return the character, rather than take a char *buff
- in theory, errno is always useful on return from a BUFF routine
- ap_bhalfduplex, B_SAFEREAD will be re-implemented using a layer I think
- chunking gone for now, will return as a layer
- ebcdic gone for now... it should be a layer
