dirstate-tree: Add map `get` and `contains_key` methods
Differential Revision: https://phab.mercurial-scm.org/D10369
The simple store doesn't escape paths robustly and can't store paths
with periods, etc. So much of this test fails with it.

Test symlink traversing when accessing history:
-----------------------------------------------
(build a changeset where the path exists as a directory)
$ hg up 0
0 files updated, 0 files merged, 1 files removed, 0 files unresolved
$ mkdir b
$ echo c > b/a
$ hg add b/a
$ hg ci -m 'add directory b'
created new head
Test that hg cat does not do anything wrong the working copy has 'b' as directory
$ hg cat b/a
c
$ hg cat -r "desc(directory)" b/a
c
$ hg cat -r "desc(symlink)" b/a
b/a: no such file in rev bc151a1f53bd

abort: path 'a/b' traverses symbolic link 'a'
[255]
try linear update including symlinked directory and its content: paths are
audited first by calculateupdates(), where no symlink is created so both
'a' and 'a/b' are taken as good paths. still applyupdates() should fail.
$ hg up -qC null
$ hg up 1
abort: path 'a/b' traverses symbolic link 'a'
[255]
$ ls ../update-symlink-out
try branch update replacing directory with symlink, and its content: the
path 'a' is audited as a directory first, which should be audited again as
a symlink.
