Subject: [PATCH] build_tools: Allow Asterisk to report git SHAs in version
 string.

Make git more attractive for managing work-in-progress.  Especially
convenient when a potential patch set needs to be tested on multiple
platforms since one can use git to keep all the test environments in sync
independent of a subversion server.

Now the Asterisk version will show the exact git SHA5 that was used when
building (still appended by "M" if there are local modifications) from a
git clone of the Asterisk repository so the developer can more easily know
what is actually under test.

You will now get this:

  $ asterisk -V
  Asterisk GIT-1698298

Instead of this:

  $ asterisk -V
  Asterisk UNKNOWN__and_probably_unsupported

This has zero impact for those not using git with the exception of an
extra test in the configure script to gather git's path.  This is
necessary to prevent "sudo make install" from failing since git may not be
in the path in make's shell environment.

(closes issue ASTERISK-20483)

-   Here is a matrix of mmap possibilities:
-	mmap private not fixed
-	mmap private fixed at somewhere currently unmapped
-	mmap private fixed at somewhere already mapped
-	mmap shared not fixed
-	mmap shared fixed at somewhere currently unmapped
-	mmap shared fixed at somewhere already mapped
-   For private mappings, we should verify that changes cannot be read()
-   back from the file, nor mmap's back from the file at a different
-   address.  (There have been systems where private was not correctly
-   implemented like the infamous i386 svr4.0, and systems where the
-   VM page cache was not coherent with the file system buffer cache
-   like early versions of FreeBSD and possibly contemporary NetBSD.)
-   For shared mappings, we should conversely verify that changes get
-   propagated back to all the places they're supposed to be.
-
-   Grep wants private fixed already mapped.
-   The main things grep needs to know about mmap are:
-   * does it exist and is it safe to write into the mmap'd area
-   * how to use it (BSD variants)  */

+	mmap private fixed at somewhere currently unmapped
+	mmap private fixed at somewhere already mapped
+	mmap shared not fixed
+	mmap shared fixed at somewhere currently unmapped
+	mmap shared fixed at somewhere already mapped
+   For private mappings, we should verify that changes cannot be read()

+   implemented like the infamous i386 svr4.0, and systems where the
+   VM page cache was not coherent with the file system buffer cache
+   like early versions of FreeBSD and possibly contemporary NetBSD.)
+   For shared mappings, we should conversely verify that changes get
+   propagated back to all the places they're supposed to be.
+
+   Grep wants private fixed already mapped.
+   The main things grep needs to know about mmap are:
+   * does it exist and is it safe to write into the mmap'd area
+   * how to use it (BSD variants)  */
