i18n: use saved object to get actual function information if available

To list up available compression types instead of
".. bundlecompressionmarker" in "hg help bundlespec" output, proxy
object "docobject" is used, because:

- current online help system requires that __doc__ of registered
  object (maybe, function) is already well formatted in reST syntax

- bundletype() method of compressionengine classes is used to list up
  available compression types, but

- __doc__ of bundletype() object (= "instancemethod") is read-only

On the other hand, hggettext requires original function object, in
order to get document location in source code.

Therefore, description of each compression types isn't yet
translatable. Even if translatable, translators should make much
effort to determine location of original texts in source code.

To get actual function information, this patch makes hggettext use
function object saved as "_origfunc", if it is available. This patch
also changes bundlecompressiontopics() side, in order to explain how
these changes work easily.

This patch is a part of preparations for making description of each
compression types translatable.
