extensions: ignore exceptions from an extension's `getversion()` method

This method is usually called when there's a stacktrace being generated, or with
`hg version -v`.  Raising another exception risks mangling the bug report info.

I hit this issue when trying to add the method to the keyring extension to
report the version of the extension and the underlying module, and ran into
demandimport issues prior to py3.8.  It seems like a wise thing to do anyway,
though unfortunately there's no convenient `ui` object around to issue a
warning.  Use 'unknown' to signal that it tried to report a version and failed,
unlike the default case of printing nothing.

Union of basic patterns:

OR expression should be reordered by weight:

  $ fileset -p optimized -s -r. 'grep("a") or a1 or grep("b") or b2'
  * optimized:

Use differencematcher for 'x and not y':

  $ fileset -p optimized -s 'a* and not a1'
  * optimized:
  (minus
    (symbol 'a*')
    (symbol 'a1'))
  * matcher:
  <differencematcher
    m1=<patternmatcher patterns='a[^/]*$'>,
    m2=<patternmatcher patterns='a1$'>>
  a2

  $ fileset -p optimized -s '!binary() and a*'
  * optimized:
  (minus
    (symbol 'a*')
    (func
      (symbol 'binary')
      None))
  * matcher:
  <differencematcher
    m1=<patternmatcher patterns='a[^/]*$'>,
    m2=<predicatenmatcher pred=binary>>
  a1
  a2

'x - y' is rewritten to 'x and not y' first so the operands can be reordered:

  $ fileset -p analyzed -p optimized -s 'a* - a1'
  * analyzed:
  (and
    (symbol 'a*')
    (not
      (symbol 'a1')))
  * optimized:
  (minus
    (symbol 'a*')
    (symbol 'a1'))
  * matcher:
  <differencematcher
    m1=<patternmatcher patterns='a[^/]*$'>,
    m2=<patternmatcher patterns='a1$'>>
  a2

  $ fileset -p analyzed -p optimized -s 'binary() - a*'
  * analyzed:
  (and
    (func
      (symbol 'binary')
      None)
    (not
      (symbol 'a*')))
  * optimized:
  (and
    (not
      (symbol 'a*'))
    (func
      (symbol 'binary')

Test files at -r0 should be filtered by files at wdir
-----------------------------------------------------

  $ fileset -r0 'tracked() and revs("wdir()", tracked())'
  a1
  b1
  b2

Test that "revs()" work at all
------------------------------

  $ fileset "revs('2', modified())"
  b2

Test that "revs()" work for file missing in the working copy/current context
----------------------------------------------------------------------------

(a2 not in working copy)

  $ fileset "revs('0', added())"
  a1
  a2
  b1
  b2

(none of the file exist in "0")

  $ fileset -r 0 "revs('4', added())"
  .hgsub
  .hgsubstate

Call with empty revset
--------------------------

  $ fileset "revs('2-2', modified())"

Call with revset matching multiple revs
---------------------------------------

  $ fileset "revs('0+4', added())"
  .hgsub
  .hgsubstate
  a1
  a2
  b1
  b2

overlapping set

  $ fileset "revs('1+2', modified())"
  b2

test 'status(...)'
=================

Simple case
-----------

  $ fileset "status(3, 4, added())"
  .hgsub
  .hgsubstate

use rev to restrict matched file
-----------------------------------------

  $ hg status --removed --rev 0 --rev 1
  R a2
  $ fileset "status(0, 1, removed())"
  a2
  $ fileset "tracked() and status(0, 1, removed())"
  $ fileset -r 4 "status(0, 1, removed())"
  a2
  $ fileset -r 4 "tracked() and status(0, 1, removed())"
  $ fileset "revs('4', tracked() and status(0, 1, removed()))"
  $ fileset "revs('0', tracked() and status(0, 1, removed()))"
  a2

check wdir()
------------

  $ hg status --removed  --rev 4
  R con.xml (no-windows !)
  $ fileset "status(4, 'wdir()', removed())"
  con.xml (no-windows !)

  $ hg status --removed --rev 2
  R a2
  $ fileset "status('2', 'wdir()', removed())"
  a2

test backward status
--------------------

  $ hg status --removed --rev 0 --rev 4
  R a2
  $ hg status --added --rev 4 --rev 0
  A a2
  $ fileset "status(4, 0, added())"
  a2

test cross branch status
------------------------

  $ hg status --added --rev 1 --rev 2
  A a2
  $ fileset "status(1, 2, added())"
  a2

test with multi revs revset
---------------------------
  $ hg status --added --rev 0:1 --rev 3:4
  A .hgsub
  A .hgsubstate
  A 1k
  A 2k
  A b2link (symlink !)
  A bin
  A c1
  A con.xml (no-windows !)
  $ fileset "status('0:1', '3:4', added())"
  .hgsub
  .hgsubstate
  1k
  2k
  b2link (symlink !)
  bin
  c1
  con.xml (no-windows !)

tests with empty value
----------------------

Fully empty revset

  $ fileset "status('', '4', added())"
  hg: parse error: first argument to status must be a revision
  [10]
  $ fileset "status('2', '', added())"
  hg: parse error: second argument to status must be a revision
  [10]

Empty revset will error at the revset layer

  $ fileset "status(' ', '4', added())"
  hg: parse error at 1: not a prefix: end
  ( 
    ^ here)
  [10]
  $ fileset "status('2', ' ', added())"
  hg: parse error at 1: not a prefix: end
  ( 
    ^ here)
  [10]
