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.

Implemented to be able to test that when writing an XML document via XMLTree
and then reading back into another XMLTree the structure is equivalent as a
general API test of pbd/xml++.h to check for breakage when changing
implementation.

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.

Adopted from Michael Beer -- GH pull-request #232 with minor changes:
* rebased on master,
* removed trailing whitespace,
* don't explicitly change saved configuration defaults (wscript)
* moved sys/wait (WNOHANG) to header include
* separate changes in GUI and lib

Massive changes all over the code to accomodate this. Many things are not finished. Consider this a backup safety commit

std:vector trumps std::list speed in all aspects: traversal, insertion

unordered_map lookup and insertion is O(1)

O(1) realloc() for use with Lua.
A standard malloc/free/realloc API is exposed for testing and other
potential use-cases.
The current configuration it's performs well for lua-metatables
(regular calls to realloc() with varying tiny chunks ~1-50 bytes)
For the use-case at hand it outperforms TLSF.
