96dbcef3fc Update TE policy and MAC text conversion routines to support partial 
label updates.  Biba and MLS already supported this.  This permits the
userland library to submit relative updates on MAC labels, rather
than submitting an entire label to replace the current label.  This
also requires changes to the MAC modules, which are forthcoming.

c1490b1966 Use '_end' symbol instead of 'end' to initialize minbrk and curbrk 
variables. Both symbols are set to the same value by the linker,
and _end symbol has less chances to clash with application defined
global symbols.

alpha, ia64 and sparc64 ports already use _end, i386 is now
consistent with them.

3b0ddae36e Rewrite locale loading procedures, so any load failure will not affect 
currently cached data.  It allows a number of nice things, like: removing
fallback code from single locale loading, remove memory leak when LC_CTYPE
data loaded again and again, efficient cache use, not only for
setlocale(locale1); setlocale(locale1), but for setlocale(locale1);
setlocale("C"); setlocale(locale1) too (i.e.  data file loaded only once).

99fbabc1a4 Always set errno to ENOMEM after malloc failed (as workaround). 
Our malloc sometimes forget to set errno, f.e. for size overflow case.

a585ff9d4b 1) Use errno to indicate faulure reason. 
2) Move incomplete check for / in locale name from env section to
loadlocale(), add check for "." and ".." too.
It allows to check any argument, not env only.
3) Redesing LOAD_CATEGORY macro to eliminate code duplication.
4) Try harder in fallback code: if old locale can't be restored,
load "C" locale
5) White space formatting, long lines, etc.

a203c58900 Introduce support for Mandatory Access Control and extensible 
kernel access control.

Extensions to libc to provide basic MAC label manipulation facilities
for userland.  These interface will be replaced in the next month
or two with more flexible interfaces, but provide sufficient support
to allow use of the Biba and MLS policies for user applications.

libc_r wrappers to follow.
