[Pianod] Build 111 - user persistence changes

[Peter Li]

Okay, this first ezxml error has to do with Linux versus BSD mman.h.  To 
get the defines (MADV_...) I would need to include (on Fedora x86) 
bits/mman.h in addition to sys/mman.h, and I would need a __USE_BSD flag.

But this is only an issue with c99; if I compile with gcc then no fuss.

The easiest "fix" is to drop MMAP from EZXML as below; not sure if that 
will cause any problem; I would assume it's an insignificant effect on 
I/O performance.  But I'll see once I get this second crypt error worked 
out.
