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.
