Several fields in cinfo is allocated memory and must be freed here
to avoid memory leakage when recreating the packet list.
Do not allocate memory for col_expr[] as this points to static strings
or other allocated strings.

Pcap-ng files don't have a per-file time stamp resolution, they have a
per-interface time stamp resolution. Add new time stamp resolution
types of "unknown" and "per-packet", add the time stamp resolution to
struct wtap_pkthdr, have the libwiretap core initialize it to the
per-file time stamp resolution, and have pcap-ng do the same thing with
the resolution that it does with the packet encapsulation.
Get rid of the TS_PREC_AUTO_XXX values; just have TS_PREC_AUTO, which
means "use the packet's resolution to determine how many significant
digits to display". Rename all the WTAP_FILE_TSPREC_XXX values to
WTAP_TSPREC_XXX, as they're also used for per-packet values.

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.

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.

by Wiretap, to indicate whether certain fields in that structure
actually have data in them.
Use the "time stamp present" flag to omit showing time stamp information
for packets (and "packets") that don't have time stamps; don't bother
working very hard to "fake" a time stamp for data files.
Use the "interface ID present" flag to omit the interface ID for packets
that don't have an interface ID.
We don't use the "captured length, separate from packet length, present"
flag to omit the captured length; that flag might be present but equal
to the packet length, and if you want to know if a packet was cut short
by a snapshot length, comparing the values would be the way to do that.
More work is needed to have wiretap/pcapng.c properly report the flags,
e.g. reporting no time stamp being present for a Simple Packet Block.
