The current checks are way too relaxed, and are more like testing
for a substring, which makes it easy for invalid paths to slip
trough, for example `/foo/var/www` is falsely tested to reside in
`/var/www`.
Passing an empty path never worked properly, it was triggering a
warning, didn't worked on Windows, and the behavior that the current
top level directory would be assumed for empty paths wasn't
documented.
Similar is true for relative paths. While they did match at one point,
this was incorrect behavior, and matching actual path fragments seems
out of scope for this method.
This change makes the `$path` argument required, requires it to be an
absolute path, and throws an exception in case a non-absolute path is
being passed.
The previous code and commit (fa3d4a0bb5)
were incorrect about invalid exchange numbers as 1-800-211-4511 is
a real phone number.
I've also removed a duplicate alternation pattern.

Use `is_uploaded_file` to prevent crafty requests that contain bogus
files from getting through. A testing stub class was necessary to avoid
making significant changes to the test suite.
I decided to leave the warning in. People who can't upgrade their
applications should at least be aware of the risks they are taking.
I'm flexible if people are strongly opposed to a warning, but I feel
that these kinds of warnings can be supressed in production if they
really are in a jam and don't care.

Fix file:// paths being mishandled on windows.
While I don't think its feasible to fix all the cases reported in #7275
as certain paths have different meaning in windows, we can fix file://
not working.

Useful for countries that do not have many of its cities, even major ones,
listed. For eg: Indonesia, only have 4 cities listed.
For backward compatibility, abbreviations will not be shown.
Note: You might need to update timezonedb for PHP 5.3
