t1450: the order the objects are checked is undefined

When a tag T points at an object X that is of a type that is
different from what the tag records as, fsck should report it as an
error.

However, depending on the order X and T are checked individually,
the actual error message can be different.  If X is checked first,
fsck remembers X's type and then when it checks T, it notices that T
records X as a wrong type (i.e. the complaint is about a broken tag
T).  If T is checked first, on the other hand, fsck remembers that we
need to verify X is of the type tag records, and when it later
checks X, it notices that X is of a wrong type (i.e. the complaint
is about a broken object X).

The important thing is that fsck notices such an error and diagnoses
the issue on object X, but the test was expecting that we happen to
check objects in the order to make us detect issues with tag T, not
with object X.  Remove this unwarranted assumption.

paint_down_to_common(): parse commit before relying on its timestamp

When refactoring the merge-base computation to reduce the pairwise
O(n*(n-1)) traversals to parallel O(n) traversals, the code forgot
that timestamp based heuristics needs each commit to have been
parsed.  This caused an empty "git pull" to spend cycles, traversing
the history all the way down to 0 (because an unparsed commit object
has 0 timestamp, and any other commit object with positive timestamp
will be processed for its parents, all getting parsed), only to come
up with a merge message to be used.

git-svn.perl: consider all ranges for a given merge, instead of only tip-by-tip

Consider the case where you have trunk, branch1 of trunk, and branch2 of
branch1.  trunk is merged back into branch2, and then branch2 is
reintegrated into trunk.  The merge of branch2 into trunk will have
svn:mergeinfo property references to both branch1 and branch2.  When
git-svn fetches the commit that merges branch2 (check_cherry_pick),
it is necessary to eliminate the merged contents of branch1 as well as
branch2, or else the merge will be incorrectly ignored as a cherry-pick.

git-svn.perl: keep processing all commits in parents_exclude

This fixes a bug where git finds the incorrect merge parent.  Consider a

Make git-svn branch patterns match complete URL

When using the {word,[...]} style of configuration for tags and branches,
it appears the intent is to only match whole path parts, since the words
in the {} pattern are meta-character quoted.

When the pattern word appears in the beginning or middle of the url,
it's matched completely, since the left side, pattern, and (non-empty)
right side are joined together with path separators.

However, when the pattern word appears at the end of the URL, the
right side is an empty pattern, and the resulting regex matches
more than just the specified pattern.

For example, if you specify something along the lines of

    branches = branches/project/{release_1,release_2}

and your repository also contains "branches/project/release_1_2", you
will also get the release_1_2 branch.  By restricting the match regex
with anchors, this is avoided.

git-svn: keep leading slash when canonicalizing paths (fallback case)

Subversion's svn_dirent_canonicalize() and svn_path_canonicalize()
APIs keep a leading slash in the return value if one was present on
the argument, which can be useful since it allows relative and
absolute paths to be distinguished.

When git-svn's canonicalize_path() learned to use these functions if
available, its semantics changed in the corresponding way.  Some new
callers rely on the leading slash --- for example, if the slash is
stripped out then _canonicalize_url_ourselves() will transform
"proto://host/path/to/resource" to "proto://hostpath/to/resource".

Unfortunately the fallback _canonicalize_path_ourselves(), used when
the appropriate SVN APIs are not usable, still follows the old
semantics, so if that code path is exercised then it breaks.  Fix it
to follow the new convention.

Noticed by forcing the fallback on and running tests.  Without this
patch, t9101.4 fails:

 Bad URL passed to RA layer: Unable to open an ra_local session to \
 URL: Local URL 'file://homejrnsrcgit-scratch/t/trash%20directory.\
 t9101-git-svn-props/svnrepo' contains unsupported hostname at \
 /home/jrn/src/git-scratch/perl/blib/lib/Git/SVN.pm line 148

With it, the git-svn tests pass again.
