we're not priming YYY, we're priming XXX *using* YYY.

Many of the complaints from checkAPI.pl for use of printf are when its embedded
in an #ifdef and checkAPI isn't smart enough to figure that out.
The other (non-ifdef) use is dumping internal structures (which is a type of
debug functionality)
Add a "ws_debug_printf" macro for printf to pacify the warnings.

master-branch libpcap now generates a reentrant Flex scanner and
Bison/Berkeley YACC parser for capture filter expressions, so it
requires versions of Flex and Bison/Berkeley YACC that support that.
We might as well do the same. For libwiretap, it means we could
actually have multiple K12 text or Ascend/Lucent text files open at the
same time. For libwireshark, it might not be as useful, as we only read
configuration files at startup (which should only happen once, in one
thread) or on demand (in which case, if we ever support multiple threads
running libwireshark, we'd need a mutex to ensure that only one file
reads it), but it's still the right thing to do.
We also require a version of Flex that can write out a header file, so
we change the runlex script to generate the header file ourselves. This
means we require a version of Flex new enough to support --header-file.
Clean up some other stuff encountered in the process.

The proto tree is needed in several cases when using Lua field extractors,
because they fetch values from the tree. Without a valid field extractor
a Lua plugin may misbehave and display wrong column info.
This fixes column issues when:
- Calling resetColumns() in Qt. This involves adding a display filter,
change time display format, change name resolution and other changes
in UI which requires column updates.
- Print summary lines.
- Export as CSV and PSML.

dfilter_macro_apply_recurse() returns either NULL or a pointer to
freshly-allocated memory, so it doesn't return a const pointer.
dfilter_macro_apply() calls dfilter_macro_apply_recurse(), so it doesn't
return a const pointer, either.
In dfilter_compile(), have separate variables for the filter handed in
and the macro-expanded filter, the former being const gchar * and the
latter being gchar *.

Have dfilter_compile() take an additional gchar ** argument, pointing to
a gchar * item that, on error, gets set to point to a g_malloc()ed error
string. That removes one bit of global state from the display filter
parser, and doesn't impose a fixed limit on the error message strings.
Have fvalue_from_string() and fvalue_from_unparsed() take a gchar **
argument, pointer to a gchar * item, rather than an error-reporting
function, and set the gchar * item to point to a g_malloc()ed error
string on an error.
Allow either gchar ** argument to be null; if the argument is null, no
error message is allocated or provided.

routine that does all the work and that takes a depth argumen, and an
external routine that calls that internal routine with a depth argument
of 0. The depth is only of use internally, to avoid infinite recursion.
When recursing with that routine, pass depth+1 as the depth value,
rather than passing depth and incrementing it afterwards; the latter
doesn't prevent infinite recursion. (Thanks and a tip of the hat to
Clang Cat for catching this.)
