Impact: extend scripts/recordmcount.pl with default alignment for SH

Set $alignment=2 for the sh architecture so that a ".align 2" directive
will be emitted for all __mcount_loc sections. Fix a whitspace error
while I'm here (converted spaces to tabs).

Impact: cleanup of recordmcount.pl

Now that more architectures are being ported to the MCOUNT_RECORD
method, there is no reason to have each declare their own arch
specific variable if most of them share the same value. This patch
creates a set of default values for the arch specific variables
based off of i386.

Fix headers_install.pl and headers_check.pl to be compatible with versions
of Perl less than 5.6.0.  It has been tested with Perl 5.005_03 and 5.8.8.
I realize this may not be an issue for most people, but there will still
be some that hit it, I imagine.  There are three basic issues:

1. Prior to 5.6.0 open() only used 2 arguments, and the versions of
the scripts in 2.6.27.1 use 3.
2. 5.6.0 also introduced the ability to use uninitialized scalar
variables as file handles, which the current scripts make use of.
3. Lastly, 5.6.0 also introduced the pragma 'use warnings'. We can use
the -w switch and be backwards compatible.

setlocalversion used to use an abbreviated git commit sha1 to generate the
tag.  This was changed in commit d882421f
"kbuild: change CONFIG_LOCALVERSION_AUTO to use a git-describe-ish format"
to use git describe to come up with a tag.  Which is nice, but git describe
sometimes can't describe the revision.
Commit 56b2f070 ("setlocalversion: do not
describe if there is nothing to describe") addressed this, but there is still
no tag generated.

So, generate a plain abbreviated sha1 tag like setlocalversion used to when
git describe comes up short.

If you use KCONFIG_ALLCONFIG (even with empty file) you get broken
allmodconfig/allyesconfig; CONFIG_MODULES gets turned off, with obvious
massive fallout.

Breakage had been introduced when conf_set_all_new_symbols() got used
for allmodconfig et.al.

What happens is that sym_calc_value(modules_sym) done in
conf_read_simple() sets SYMBOL_VALID on both modules_sym and MODULES.
When we get to conf_set_all_new_symbols(), we set sym->def[S_DEF_USER]
on everything, but it has no effect on sym->curr for the symbols that
already have SYMBOL_VALID - these are stuck.

Solution: use sym_clear_all_valid() in there.  Note that it makes
reevaluation of modules_sym redundant - sym_clear_all_valid() will do
that itself.

The recordmcount script requires that the actual arch is passed in.
This works well when ARCH=i386 or ARCH=x86_64 but does not handle the
case of ARCH=x86.

This patch adds a parameter to the function to pass in the number of
bits of the architecture. So that it can determine if x86 should be
run for x86_64 or i386 archs.

When bootgraph.pl parses a file, it gives one row for each initcall's
pid.  But they are displayed in random (perl hash) order.  Let's
sort the pids by the start time of their first initcall instead.

This helps trace module initcalls, where each has a separate pid.
bootgraph.pl will show module initcalls during the initramfs; it may
also be adapted to show subsequent module initcalls.
