Larry Doolittle 8ea3b6b0b8 header includes for gcc-4.3 compatibility 
minimal changes required to build without error
tested with gcc-4.3 (Debian 4.3-20071130-1) 4.3.0 20071130 (experimental)

Stephen Williams 7975e14b5c 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.

Martin Whitaker 05a6e69d2d Support nested generate schemes. 
This patch adds support for nested loops and if-else decisions in generate
statements.

Cary R 35df445db1 Initialize all range variables in the constructor to avoid false asserts. 
This would have never been a problem with the actual circuit generated.
The problem was that the assert was checking values that had never been
set. The constructor now explicitly sets these values to zero and while
I was at it I added a couple more asserts.

Cary R 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.

Stephen Williams 396ffd1cdd Add support for conditional generate. In the process, fix bugs 
related to generate used multiple times by multiple scopes causing
spurious generation results.
