Realign generation flags to correspond to IEEE1364 nomenclature.
...
IEEE1364 has specific names for the various generations of Verilog that
are supported. Icarus Verilog should stick to those names for selection
the language feature set.
In the process, the extensions that were tied to the 2x generations
are pulled out out and given their own enable flags. The makes all the
feature control more regular and understandable.

Add infrastructure for enabling Verilog-AMS
...
Add the -gverilog-ams flag to the driver, and the begin_keywords support
for VAMS-2.3 keywords. With this, the infrastructure is in place to
start pulling in features from Verilog-AMS.

Support for the begin_keywords directive.
...
The begin_keywords directive allows the source code to select keyword
subsets so that a bit of code that uses identifiers that class with a
newer version of the standard can still be compiled.

`delay_mode_zero and `line as ignored compiler directives.

Fix malloc/free and new/delete problems, plus some initializations.
...
This patch fixes some allocation problems (mostly in the parser
and lexor relating to identifiers). It also fixes a couple places
where uninitialized variables were used. All found with valgrind.
There are still 100 tests that have problems. Many of these appear
to be related.

LineInfo uses perm_string for path.
...
Rework the handling of file names to use a perm_string heap to hold
the file names, instead of the custom file name heap in the lexor.
Also rename the get_line to get_fileline to reflect its real duties.
This latter chage touched a lot of files.

Check for extra digits in sized binary, octal and hex constants.
...
Print out a warning if extra digits are given for sized binary, octal
or hex constants. Decimal constants are very hard since we never
calculate the true number of bits the digits represent, so for now
decimal constants are not checked.
