revset: add an optimised baseset.__contains__ (issue4371)

The baseset class is based on a python list. This means that base.__contains__
was absolutely as crappy as list.__contains__. We now rely on __contains__ from
the underlying set.

This will avoid having to explicitly convert the baseset to a set (using
baseset.set()) whenever one want fast membership test.

Apparently there is already code that forgot to do such conversions since we
observe a massive speedup in some test.

revset #25: roots((0::) - (0::tip))
0) wall 2.079454 comb 2.080000 user 2.080000 sys 0.000000 (best of 5)
1) wall 0.132970 comb 0.130000 user 0.130000 sys 0.000000 (best of 65)

No regression is observed in benchmarks.

This change improve the issue4371 back to acceptable situation (but are still
slower than manual substraction)

  $ hg up -qr null
  $ hg up -qr 2
)

Systematic testing of merges involving largefiles:

Ancestor: normal  Parent: normal=  Parent: large   result: large
Ancestor: normal  Parent: normal2  Parent: large   result: ?
Ancestor: large   Parent: large=   Parent: normal  result: normal
Ancestor: large   Parent: large2   Parent: normal  result: ?

All cases should try merging both ways.
"=" means same file content.

Prepare test repo:

  $ hg init merges
  $ cd merges
  $ touch f1
  $ hg ci -Aqm "0-root" --config extensions.largefiles=!

Ensure that .hg/largefiles isn't created before largefiles are added

  $ chmod 555 .hg

  $ hg status

  $ chmod 755 .hg
