When the lexer encounters an unexpected character in a policy source file, it prints a warning, discards the character and moves on. In some build environments, these characters could be a symptom of an earlier problem, such as unintended results of expansion of preprocessor macros, and the ability to have the compiler halt on such issues would be helpful for diagnosis.

If - is given as filename for -o option, checkpolicy
writes the policy to standard output. This helps users
to read policy.conf and/or CIL policy file with pager
like less command:
$ checkpolicy -M -F -b /sys/fs/selinux/policy -o - | less
The users don't have to make a temporary file.
/dev/stdout can be used instead. However, - reduces the number of
typing for the purpose. Using - for standard output (and/or standard
input) is popular convention.
Change(s) in v2:
* Check the availability of output stream only when opening
a regualar file. Suggested by Stephen Smalley <sds@tycho.nsa.gov>.

Add the command-line option 'O' to checkpolicy to cause kernel policies
to be optimized by calling policydb_optimize() before being written out.
This option can be used on conf files and binary kernel policies, but
not when converting a conf file to CIL.

[omosnace: directly use policydb_optimize() as also the rest of code already uses
other policydb_*() functions...]

Use the same option "-C" used to ouput CIL from a policy.conf, but now
generate CIL from a binary policy instead of giving an error.i
Use the option "-F" to generate a policy.conf file from a binary policy.

Add support to checkpolicy and checkmodule for generating CIL as their
output.
Add new options "-C" and "--cil" to specify CIL as the output format.

This patch is proposed to solve Ticket #1 [1672486] (command line
binaries should support --version and --help).
It adds handling of -h, -V and the long formats --help and --version to
all binaries (checkpolicy/checkmodule).
It also adds handling of long options for some of the available options.
Manual pages have also been updated accordingly (and a few undocumented
options have been documented).
