Update lex/yacc builds to be consistent and to support parallel builds
...
Not all the lex/yacc (flex/bison) targets were using a consistent syntax.
This patch fixes that and explicitly serializes the *.c/*.cc and *.h build.
Not doing this was causing problem when using make -j. The issue appears to
be that if two targets are specified for a rule (e.g. file.cc file.h: file.y)
make does not realize they are both built by the same call so the rule is
executed twice. Once for the .cc target and once for the .h target. This is
not a problem for a serial build. To work around this only use the .c/.cc
file in the main target and then make the .h file depend on the .c/.cc file
as a sub-target.

Use mkdir() instead of _mkdir() for MinGW
...
MinGW-w64 requires the use of mkdir() and MinGW-w32 appears to support
both so use mkdir() to allow compilation to work with both versions.

Fix Cygwin compile problem (replace abs() call with ?:
...
This patch fixes a compile problem in Cygwin where there are two
definitions for abs() that do not match so the C++ code doesn't know
which one to call. To avoid the whole mess replace the call to abs()
with the appropriate ?: construct.

Compiler fixes for MinGW.
...
In MinGW, when parameters are passed to vhdlpp by ivlpp, single quotes
are treated as ordinary characters. Use double quotes instead, as is
done in the driver.
Also, MinGW does not have a standard mkdir() function, so we need to
convert calls to mkdir() into calls to _mkdir().

Put off array bound evaluation / describe entity generics as parameters

Entity generics are easily implemented as module parameters, so make
it so. Give the parameters their default values from the generic declaration.
Array bounds may use values that cannot be evaluated right away, so
put off their evaluation.

the C routines, it defines the pointer as a class for C++ and as struct for
C and it removes a namespace std duplication.
