mercurial: add debugextensions command (issue4676)

Add debugextensions command to help users debug their extension
problems. If there are no extensions command prints nothing,
otherwise it prints names of extension modules. If quiet or
verbose option is not specified it prints(after extensions name)
last version of mercurial in which given module was tested for
non internal modules or not tested with user mercurial version.

If verbose is specified it prints following information for every
extension: extension name, import source, testedwith and buglink
information.

Extensions are printed sorted by extension name.

This file focuses mainly on updating largefiles in the working
directory (and ".hg/largefiles/dirstate")

Test that update also updates the lfdirstate of 'unsure' largefiles after
hashing them:

The previous operations will usually have left us with largefiles with a mtime
within the same second as the dirstate was written.
The lfdirstate entries will thus have been written with an invalidated/unset
mtime to make sure further changes within the same second is detected.
We will however occasionally be "lucky" and get a tick between writing
largefiles and writing dirstate so we get valid lfdirstate timestamps. The
following verification is thus disabled but can be verified manually.

#if false
  $ hg debugdirstate --large --nodate
  n 644          7 unset               large1
  n 644         13 unset               large2
#endif

Wait to make sure we get a tick so the mtime of the largefiles become valid.

  $ sleep 1

A linear merge will update standins before performing the actual merge. It will
do a lfdirstate status walk and find 'unset'/'unsure' files, hash them, and
update the corresponding standins.
Verify that it actually marks the clean files as clean in lfdirstate so
we don't have to hash them again next time we update.

  $ hg up
  0 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ hg debugdirstate --large --nodate
  n 644          7 set                 large1
  n 644         13 set                 large2

Test that lfdirstate keeps track of last modification of largefiles and
prevents unnecessary hashing of content - also after linear/noop update

  $ sleep 1
  $ hg st
  $ hg debugdirstate --large --nodate
  n 644          7 set                 large1
  n 644         13 set                 large2

changed, even if it is aborted by conflict of other.

Test that "hg status" doesn't show removal of largefiles not managed
in the target context.

  $ hg remove largeX
  $ hg status -A largeX

  $ hg status -A --rev '.^1' largeX

#if execbit

Test that "hg status" against revisions other than parent notices exec
bit changes of largefiles.

  $ hg update -q -C 4

(the case that large2 doesn't have exec bit in the target context but
in the working context)

  $ chmod +x large2
  $ hg status -A --rev 0 large2
  M large2
  $ hg commit -m 'chmod +x large2'

(the case that large2 has exec bit in the target context but not in
the working context)

  $ echo dummy > dummy
  $ hg add dummy
  $ hg commit -m 'revision for separation'
  $ chmod -x large2
  $ hg status -A --rev '.^1' large2
  M large2

#else

Test that "hg status" against revisions other than parent ignores exec
bit correctly on the platform being unaware of it.

  $ hg update -q -C 4

Test that "hg convert" avoids copying largefiles from the working
directory into store, because "hg convert" doesn't update largefiles
in the working directory (removing files under ".cache/largefiles"
forces "hg convert" to copy corresponding largefiles)
