When dissecting with columns TCP dissector spends
around 1/4 time in col_append_fstr(), add col_append_lstr()
and do formatting by ourselves.

We have callgrind benchmarks which shows that col_add_fstr() takes
5% of Ir count cause of formatting done in g_vsnprintf().
New col_add_lstr() can be used in few dissectors without much ugliness,
and it should be a little faster.

Cast away some implicit 64-bit-to-32-bit conversion errors due to use of
strtol() and strtoul().
Change some data types to avoid those implicit conversion warnings.
When assigning a constant to a float, make sure the constant isn't a
double, by appending "f" to the constant.
Constify a bunch of variables, parameters, and return values to
eliminate warnings due to strings being given const qualifiers. Cast
away those warnings in some cases where an API we don't control forces
us to do so.
Enable a bunch of additional warnings by default. Note why at least
some of the other warnings aren't enabled.
randpkt.c and text2pcap.c are used to build programs, so they don't need
to be in EXTRA_DIST.
If the user specifies --enable-warnings-as-errors, add -Werror *even if
the user specified --enable-extra-gcc-flags; assume they know what
they're doing and are willing to have the compile fail due to the extra
GCC warnings being treated as errors.

- Change apply / prepare / ... as filter to use the field's value, which
is now stored in fdata as well as cinfo. Now we don't have to reprocess
the entire packet list when using these features. This also prevents
the use of these features from overwriting custom column information.
(custom columns can now be used in apply / prepare ... as filter)
- Break col_expr and col_expr_val out into a struct that is included not only
in cinfo, but now also fdata.
- Have col_custom_set_fstr() quote FT_STRING & FT_STRINGZ when storing the
col_expr_val value (for filter creation).

- COL_DELTA_CONV_TIME which is used to display the delta time from the previous frame of the conversation
It also adds the function "col_set_time()" to "epan/column-utils.[ch]" which can be called from within a dissector to set either of these two columns to the appropiate time.
Last but not least, it lets the tcp-dissector make use of these two columns.

instead of calling the tcp analysis (and prepend colingo) eitehr after the subdissector returned normally or if an exception caused by a subdissector was rised.
this as a sideffect caused tcp analysis data to be overwritten if the subdissector caused any output to the info column. (and made tcp analysis suboptimal)
this change adds a new function col_prepend_fence_fstr() that will prepend
the info column with the string and also, if there was no fence already defined, create a fence and set it after the prepended col info text.
This way, even if the subdissectors generate and rewrite col info, the tcp analysis data will still be displayed on the info column.

Fix some more calls to "expert_add_info_format()" to pass it a format

Don't record BoundsError exceptions as expert events - they merely
reflect a capture done with a snapshot length too short to capture all

to "protect" what's currently in the column, so that attempts to clear
the column will only clear stuff after the fence and attempts to
overwrite the column will append stuff after the fence. This, for
example, allows a dissector to arrange that the Info column contain
information for its protocol and for protocols running atop it.

item to look more-or-less like a PPP packet, just dissect it in place
and hand off to the appropriate subdissector using the PPP dissector's
handoff table (which we export, along with its value_string table for
protocol IDs, which we use to report the protocol ID symbolically).
This means there's no point in having a configurable option to control
whether to do that tweaking; make it an obsolete option.
Bring "col_get_writable()" back from the dead, and have the GTP
dissector save the current "writable" flag for columns, mark the columns
non-writable before calling the subdissector for the PPP configuration
protocol, and restore the state of the writable flag, rather than
putting the columns back after the PPP configuration protocol's
dissector is done.
Fix some more typos in comments.
Don't register the IP dissector in the "ppp.protocol" table in the GTP
dissector's handoff registration routine - it's already being done in
the IP dissector's handoff routine.
Fix the name for CHAP to match what RFC 1994 calls it (if the name

http://mail-index.netbsd.org/netbsd-help/1996/05/16/0011.html

Protocol (CHAP)").
