Remove redundant NULL checks before free()/delete
The ISO C and C++ standards guarantee that it's safe to call these
on a NULL pointer, so it's not necessary for the calling code to
also check.

It was not obvious to at least one person that namespaces need to be
unignored just like classes and methods. Add an explicit reference to
that in the docs.
Also add something to unignore all classes in the example that shows how
to ignore all classes, as that might not be obvious.
Fixes#193
In the example for ignoring everything, it didn't show how to undo the
ignore all, and the obvious '%rename("") ""' didnt work.
'"%rename("%s") ""' is the right way to do that, so add it to the
example.
Fixes#2173
The example I recently added about renaming didn't compile. Here's the
fix.
There was also a use of the term "override" which should have been
changed to "replace".
Document extern template functions support.
Extern templates result in new warning to differentiate
from template explicit instantiation definition warning.
As discussed and agreed in #1629, it's become hard to test with Perl
5.6 or earlier, such old versions are no longer in active use, and
4.1.0 is an appropriate time to make such a change.
I've dropped the compatibility code that was obvious to me, but there's
probably more that can be cleaned up now.
With modern PHP it only works with the CLI version of PHP, so it's
better to direct users to load the extension via "extension=" in
php.ini.
Suggested by ferdynator in #1529.
These were officially deprecated in 2001, and attempts to use them have
resulted in a warning (including a pointer to what to update them to)
for most if not all of that time.
Fixes#1984
A PHP exception now gets translated to a C++ exception to skips over C++
code to get back to PHP, avoiding the need to gate every directorout
typemap on EG(exception).
This isn't really workable since PHP doesn't support intercepting
accesses to global variables (nor to static class properties, so
we can't wrap C/C++ global variables that way either).
The _get() and _set() function wrappers actually work and have
been generated for a very long time.
