Stephen Smalley 9eb9c93275 Get rid of security_context_t and fix const declarations.
In attempting to enable building various part of Android with -Wall -Werror,
we found that the const security_context_t declarations in libselinux
are incorrect; const char * was intended, but const security_context_t
translates to char * const and triggers warnings on passing
const char * from the caller.   Easiest fix is to replace them all with
const char *.  And while we are at it, just get rid of all usage of
security_context_t itself as it adds no value - there is no true
encapsulation of the security context strings and callers already
directly use string functions on them.  typedef left to permit
building legacy users until such a time as all are updated.

This is a port of Change-Id I2f9df7bb9f575f76024c3e5f5b660345da2931a7
from Android, augmented to deal with all of the other code in upstream
libselinux and updating the man pages too.
