help: add internals.extensions topic

I think it's better to include the API overview in core as we now have the
internals section in our help system.

Retrieved from the wiki, and formatted as reST. Several wiki links are
removed since they are invalid in the help. The sections about example
extension are removed at all as they seemed too verbose.

Test for showing working of allfiles flag

  $ hg init sng

  $ echo "unmod" >> um
  $ hg ci -A -m "adds unmod to um"

  adding new
  $ hg grep -r "." "unmod"
  [1]
  $ hg grep -r "." "unmod" --all-files
  um:1:unmod

With --all-files, the working directory is searched by default

  $ echo modified >> new
  $ hg grep --all-files mod
  new:modified
  um:unmod

 which can be overridden by -rREV

  $ hg grep --all-files -r. mod
  um:1:unmod

commands.all-files can be negated by --no-all-files

  $ hg grep --config commands.grep.all-files=True mod
  new:modified
  um:unmod
  $ hg grep --config commands.grep.all-files=True --no-all-files mod
  um:0:unmod

--diff --all-files makes no sense since --diff is the option to grep history

  $ hg grep --diff --all-files um
  abort: --diff and --all-files are mutually exclusive
  [255]

but --diff should precede the commands.grep.all-files option

  $ hg grep --config commands.grep.all-files=True --diff mod

Change Default of grep by ui.tweakdefaults, that is, the files not in current

  > tweakdefaults = True

  $ echo "some text">>file1
  $ hg add file1
  $ hg commit -m "adds file1"
  $ hg mv file1 file2

wdir revision is hidden by default:

  $ hg grep "some"
  file2:some text

but it should be available in template dict:

  $ hg grep "some" -Tjson
