Change the logic in modpost so we identify all the
bad combinations of sections that refer to other
sections.
Compared to the previous approach we are much less
dependent on knowledge of what additional sections
the tool chain uses and thus we can keep the false
positives low.
The implmentation is changed to use a table based
lookup and we now check all combinations in first
pass so we no longer need separate passes for init
and exit sections.
Tested that the same warnings are generated for
an allyesconfig build without CONFIG_HOTPLUG.

The relocation record sometimes contained an address
which was not an exactly match for a symbol.
Implment some simple logic such that if there
is a symbol within 20 bytes of the address contained
in the relocation record then print the name of this
symbol.
With this change modpost could find symbol names
for the remaining .init.text symbols in my
allyesconfig build for x86_64.

userlands and cross-compilers, but it will not hurt kernel kconfig
either. PTXdist menuconfig now works on Windows linked with PDCurses and
compiled using MinGW - there is no termios and signals.

Switch from doing our own parsing of command line arguments to
using getopt(3) to do it. Aside from simplifying things, this allows us to
specify multiple arguments; the old code could only accept two arguments
(input_mode and kconfig name).
Note some subtle changes:
- The argument '-?' is no longer supported.
- '-h' is not treated as an error, so output goes to stdout, and we
exit with '0'.
- There is no compatibility checking amongst arguments; the last option
will simply override earlier options. For example, 'conf -n -y foo'
is perfectly valid now (input_mode will be set_yes). Previously, that
would have been an error ("can't find file -y").

When multiple built-in modules (especially drivers) provide the same
capability, they're prioritized by link order specified by the order
listed in Makefile. This implicit ordering is lost for loadable
modules.
When driver modules are loaded by udev, what comes first in
modules.alias file is selected. However, the order in this file is
indeterministic (depends on filesystem listing order of installed
modules). This causes confusion.
The solution is two-parted. This patch updates kbuild such that it
generates and installs modules.order which contains the name of
modules ordered according to Makefile. The second part is update to
depmod such that it generates output files according to this file.
Note that both obj-y and obj-m subdirs can contain modules and
ordering information between those two are lost from beginning.
Currently obj-y subdirs are put before obj-m subdirs.
Sam Ravnborg cleaned up Makefile modifications and suggested using awk
to remove duplicate lines from modules.order instead of using separate
C program.
