Use std::vector::reserve to improve performance of adding properties
...
The number of properties per node roughly corresponds to the number of members
of the class the node is representing and should be fairly low.
Use std::vector::reserve to prevent reallocation on insert for most node types,
there are exceptions like Region(~40 properties).
This seems worth it as part(maybe 1/10th of the total time) of saving a Session
is a combination of what occurs in "Create" and "Write" in this test.

Remove PropertyMap from XMLNode class
...
It appears that there is no performance benefit from storing properties in a
map for faster lookup or it is counteracted by the penalty of storing and
maintaining the additional data structure.

Move PBD::canonical_path to pbd/file_utils.h/cc and reimplement for Windows
...
This fixes the libpbd testCanonicalPathUTF8 and libardour
open_session_utf8_path unit tests
You can now have Sessions with localized names containing characters that
aren't in the system codepage on Windows.
It also fixes the issue where a Session would not open when it was moved into a
path with characters that aren't in the system codepage.
The only use case for calling canonical_path/realpath on the session path
AFAICT is for resolving relative paths that are passed via the command
line/terminal. I'm doubtful that works correctly on Windows because of
character encoding issues with the current API we use for that(not glib), so it
is slightly ironic that this issue was caused by an incorrect implementation of
a function that is not really necessary on Windows at this point in time.

Add test for PBD::canonical_path on Windows using utf8 strings
...
This currently fails because the windows only realpath implementation in
pbd/pathexpand.cc, which is called from PBD::canonical_path to resolve the path
uses Glib::locale_from/to_utf8. As I demonstrated in the
testOpenFileUTF8Filename test case Glib::locale_from/to_utf8 are not the
correct functions to use for this use case as it converts to/from utf-8 to the
locale's current character encoding. On Windows this is most often a single
byte encoding such as Windows-1252 and conversion will fail if the path
contains any characters that are not in system codepage.

Give the Windows MMTimer test a better chance of passing
...
The default scheduling on windows seems fairly erratic or is at least in the
VM that I'm running these tests on, so increase the timing slack a bit so the
test has a better chance of passing. It is still quite easy for it to fail
though, especially if you for instance manipulate the terminal window somehow
while running the tests but it does not really matter in any case as this test
serves its purpose in testing the PBD::MMTimers API.
