revset-rangeset: call 'getset' on a 'fullreposet'

Calling 'baseset(repo.changelog)' builds a list for all revisions in
the repo. And we already have the lazy and efficient 'fullreposet'
class for this purpose.

This gives us the usual benefit ofs the fullreposet:

revset) 10:100
before) wall 0.002774 comb 0.000000 user 0.000000 sys 0.000000 (best of 797)
after)  wall 0.001977 comb 0.000000 user 0.000000 sys 0.000000 (best of 1244)

revset) parents(10):parents(100)
before) wall 0.005054 comb 0.000000 user 0.000000 sys 0.000000 (best of 481)
after)  wall 0.002060 comb 0.000000 user 0.000000 sys 0.000000 (best of 1056)

Tests of 'hg status --rev <rev>' to make sure status between <rev> and '.' get
combined correctly with the dirstate status.

Sets up a history for a number of files where the filename describes the file's
history. The first two letters of the filename describe the first two commits;
the third letter describes the dirstate for the file. For example, a file called
'amr' was added in the first commit, modified in the second and then removed in
the dirstate.

These codes are used for commits:
x: does not exist
a: added
c: clean
m: modified
r: removed

These codes are used for dirstate:
d: in dirstate, but deleted from disk
f: removed from dirstate, but file exists (forgotten)
r: removed from dirstate and disk
q: added, but deleted from disk (q for q-rious?)
u: not in dirstate, but file exists (unknown)
