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subsets so that a bit of code that uses identifiers that class with a
newer version of the standard can still be compiled.

c38e8182c2
Add checks that verify an always statement has delay.
...
This patch adds check to determine if an always block has delay
in it or not. If there is no delay a runtime infinite loop will
occur. For the indeterminate case it will print a warning message
if the new -Winfloop flag is given. This flag is not part of the
-Wall check!

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.

synth* functors.

b69c4c9a2c
Fix range handling/checking and add a flag to allow deprecated port syntax.
...
This patch is rather large and fixes a couple of problems. The major
change is that instead of keeping all the range specifications in
a list that is later processed the information is now kept as
individual entries for the port and net definitions. This allows
easier checking for multiple definitions (pr1660028), more
detailed error messages and the ability to pass the now deprecated
style of a scalar I/O definition used with a vectored net definition.
These changes did require extra code to prevent a single definition
from setting the range values in more than on place.
When using the new ANSI-C style of port declarations (1364-2001 12.3.4
list_of_port_declarations) the compiler ensures that you do not
redeclare the port in the body (it is already completely defined).
This caught a few errors in the test suite (pr859 and sqrt32*).
The flag to disable the normal port checking and allow the deprecated
port syntax is -gno-io-range-error. This will print a warning for the
case of a scalar port with a vectored definition in the body. All
other cases are still considered an error.
