When searching for symbols, return the symbols sorted by relevance.

Sorting is done as thus:
  - first, symbols that match exactly
  - then, alphabetical sort

Since the search can be a regexp, it is possible that more than one symbol
matches exactly. In this case, we can't decide which to sort first, so we
fallback to alphabeticall sort.

Explain this (new!) sorting heuristic in the documentation.

Changes v1->v2:
  - drop the previous, complex heuristic in favour of a simpler heuristic
    that is both easier to understand, *and* to maintain (Jean)
  - explain sorting heuristic in the doc  (Jean)

Ever since commit 45f035ab9b8f ("CONFIG_HOTPLUG should be always on"),
it has been basically impossible to build a kernel with CONFIG_HOTPLUG
turned off.  Remove all the remaining references to it.

Pull misc kbuild updates from Michal Marek:
 "Non-critical kbuild changes:

   - make coccicheck improvements, but no new semantic patches this time

   - make rpm improvements

   - make tar-pkg change to include the architecture in the filename.

     This is a deliberate incompatibility, but nobody has complained so
     far and it is useful if you build for different architectures.  It
     also matches what the deb-pkg and rpm-pkg targets produce.

   - kbuild documentation fix"

* 'misc' of git://git.kernel.org/pub/scm/linux/kernel/git/mmarek/kbuild:
  rpm-pkg: Remove pointless set -e statements
  rpm-pkg: Always regenerate the specfile
  rpm-pkg: Do not write to the parent directory
  rpm-pkg: Do not package the whole source directory
  buildtar: Add ARCH to the archive name
  Coccinelle: Fix patch output when coccicheck is used with M= and C=
  Coccinelle: Add support to the SPFLAGS variable
  Coccinelle: Cleanup the setting of the FLAGS and OPTIONS variables
  Coccinelle: Restore coccicheck verbosity in ONLINE mode (C=1 or C=2)
  scripts/package/Makefile: compare objtree with srctree instead of test KBUILD_OUTPUT
  doc: change example to existing Makefile fragment
  scripts/tags.sh: Add magic for OFFSET and DEFINE

  kconfig: fix lists definition for C++
  Revert "kconfig: fix randomising choice entries in presence of KCONFIG_ALLCONFIG"
  kconfig: implement KCONFIG_PROBABILITY for randconfig
  kconfig: allow specifying the seed for randconfig

  merge_config.sh: Avoid creating unnessary source softlinks
  kconfig: optionally use pkg-config to detect ncurses libs
  menuconfig: optionally use pkg-config to detect ncurses libs

Currently the odds to set each symbol is (rounded):
    booleans:   y: 50%          n: 50%
    tristates:  y: 33%  m: 33%  n: 33%

Introduce a KCONFIG_PROBABILITY environment variable to tweak the
probabilities (in percentage), as such:
    KCONFIG_PROBABILITY     y:n split           y:m:n split
    -----------------------------------------------------------------
[1] unset or empty          50  : 50            33  : 33  : 34
[2] N                        N  : 100-N         N/2 : N/2 : 100-N
    N:M                     N+M : 100-(N+M)      N  :  M  : 100-(N+M)
    N:M:L                    N  : 100-N          M  :  L  : 100-(M+L)

[1] The current behaviour is kept as default, for backward compatibility

For reproducibility, it can be useful to be able to specify the
seed to use to seed the RNG.

Add a new KCONFIG_SEED environment variable which can be set to
the seed to use:
    $ make KCONFIG_SEED=42 randconfig
    $ sha1sum .config
    70a128c8dcc61303069e1be352cce64114dfcbca  .config
    $ make KCONFIG_SEED=42 randconfig
    $ sha1sum .config
    70a128c8dcc61303069e1be352cce64114dfcbca  .config

It's very usefull for eg. debugging the kconfig parser.

The kbuild's ld-option function is broken because
the command
  $(CC) /dev/null -c -o "$$TMPO"
does not create object file!

I have used a relatively old mips gcc 3.4.6 cross-compiler
and a relatively new gcc 4.7.2 to check this fact
but the results are the same.

EXAMPLE:
  $ rm /tmp/1.o
  $ mips-linux-gcc /dev/null -c -o /tmp/1.o
  mips-linux-gcc: /dev/null: linker input file unused because linking not done
  $ ls -la /tmp/1.o
  ls: cannot access /tmp/1.o: No such file or directory

We can easily fix the problem by adding
the '-x c' compiler option.

EXAMPLE:
  $ rm /tmp/1.o
  $ mips-linux-gcc -x c /dev/null -c -o /tmp/1.o
  $ ls -la /tmp/1.o
  -rw-r--r-- 1 antony antony 778 Apr  2 20:40 /tmp/1.o

Also fix wrong ld-option example.

Pull kconfig changes from Michal Marek:
 "I forgot to send a pull request in time for the v3.8-rc1 merge window,
  so the list is a bit longer this time:

   - menuconfig enables extended colors in ncurses if the wide-character
     version is used.

   - CONFIG_ prefix can be specified in the environment to make life
     easier for people using kconfig multiple times in a single tree (no
     functional change in the kernel kconfig usage).

   - kconfig aborts on OOM.

   - inputboxes in menuconfig allow to move the cursor.

   - menuconfig has Save/Load buttons now.

   - xconfig build fix with new g++ and Qt3.

   - nconfig color scheme fix and help text update.

   - make oldconfig prints newlines when output is redirected.

   - some other minor fixes."
