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.

.SH "NAME"
setfilecon, fsetfilecon, lsetfilecon \- set SELinux security context of a file
.
.SH "SYNOPSIS"

.BI "int setfilecon(const char *" path ", char * "con );
.sp
.BI "int setfilecon_raw(const char *" path ", char * "con );

.SH "DESCRIPTION"
.BR setfilecon ()
sets the security context of the file system object.
.BR lsetfilecon ()
is identical to setfilecon, except in the case of a symbolic link, where the
link itself has it's context set, not the file that it refers to.
.BR fsetfilecon ()
is identical to setfilecon, only the open file pointed to by filedes (as
returned by
.BR open (2))
has it's context set in place of path.
.BR setfilecon_raw (),
.BR lsetfilecon_raw (),
and
.BR fsetfilecon_raw ()
behave identically to their non-raw counterparts but do not perform context
translation.
.
.SH "RETURN VALUE"
On success, zero is returned. On failure, \-1 is returned and
.I errno
is set appropriately.
.
.SH "ERRORS"
If there is insufficient space remaining to store the extended
attribute,
.I errno
is set to either
.BR ENOSPC ,
or
.B EDQUOT
if quota enforcement was the cause.
If extended attributes are not supported by the filesystem, or are disabled,
.I errno
is set to
.BR ENOTSUP .
The errors documented for the
.BR stat (2)
system call are also applicable here.
