Peter Wu eec3ce3bb2 dfilter: fix memory leaks on dfilter compile errors involving a set
If a display filter contains a set for the set membership operator and
an error occurs, then gen_relation_in() (called via dfw_gencode() will
not take ownership of the set and a memory leak occurs.

Fix this by implementing a free callback for STTYPE_SET nodes which
frees unclaimed data. Add tests to verify the effectiveness, ASAN no
longer complains after this fix.

Peter Wu e8e60df4ce dfilter: fix memory leaks if a dfilter fails to compile
A display filter can contain values such as strings, numbers, etc. These
are internally stored in a fvalue_t structure. While compiling a display
filter, it will store a fvalue_t in a node of type STTYPE_FVALUE.

These nodes are created while parsing the dfilter in dfilter_compile().
If the semantic check and conversion (dfw_semcheck()) succeeds, it will
transfer the values of the parsed tree to dfw_gencode(). After that,
dfwork_free will dispose the tree while a compiled dfilter code remains.
When the dfilter code is destroyed, it will free the values too.

However, when dfw_semcheck() fails (for example, due to an illegal
filter such as "len(badname)==1"), it will skip "dfw_gencode()" and
consequently the fvalue data is not transferred nor freed. Fix this by
always freeing the data (unless the data was stolen by dfw_gencode()).

Fixes a memory leak reported for case_dfunction_string::test_fail_2
which was detected by ASAN.

Peter Wu 6144951380 dfilter: fix memleaks with functions and slice operator
Running tools/dfilter-test.py with LSan enabled resulted in 38 test
failures due to memory leaks from "fvalue_new". Problematic dfilters:
- Return values from functions, e.g. `len(data.data) > 8` (instruction
  CALL_FUNCTION invoking functions from epan/dfilter/dfunctions.c)
- Slice operator: `data.data[1:2] == aa:bb` (function mk_range)

These values end up in "registers", but as some values (from READ_TREE)
reference the proto tree, a new tracking flag ("owns_memory") is added.

Add missing tests for some functions and try to improve documentation.

Peter Wu 699ee5dc52 dfilter: make spaces around ".." optional in display filter
For numeric values such as port numbers, "4430..4434" looks more
natural than "4430 .. 4434", so support that.

To make this possible, the display filter syntax needs to be restricted.
Assume that neither field names nor values can contain "..". The display
filter `data contains ..` will now be considered a syntax error and must
be written as `data contains ".."` instead. More generally, all values
that contain ".." must be quoted.

Other than the ".." restriction, the scanner deliberately accepts more
characters that can potentially form invalid input. This is to prevent
accidentally splitting input in multiple tokens.  For example, "9.2." in
"frame.time_delta in {9.2.}" is currently parsed as one token and then
rejected because it cannot be parsed as time. If the scanner was made
stricter, it could treat it as two tokens (floats), "9." and "2." which
has different meaning for the set membership operator.

An unhandled edge case is "1....2" which is parsed as "1 .. ..  2" but
could have been parsed as "1. .. .2" instead. A float with trailing dots
followed by ".." seems sufficiently weird, so rejection is fine.

Allow "tcp.srcport in {1662 1663 1664}" to be abbreviated to
"tcp.srcport in {1662 .. 1664}". The range operator is supported for any
field value which supports the "<=" and "=>" operators and thus works
for integers, IP addresses, etc.

The naive mapping "tcp.srcport >= 1662 and tcp.srcport <= 1664" is not
used because it does not have the intended effect with fields that have
multiple occurrences (e.g. tcp.port). Each condition could be satisfied
by an other value. Therefore a new DVFM instruction (ANY_IN_RANGE) is
added to test the range condition against each individual field value.

João Valverde 9bba3866ff CMake: Allow user build flags to override default build flags
Autotools has the very useful feature by design of allowing the user
to override the default build flags (you break it you keep it).

Apparently CMake applies COMPILE_OPTIONS target property after
CMAKE_{C,CXX}_FLAGS so that doesn't work here. Prepend our flags to those
variables instead to make it work then.

Specific target flag overrides can still be added with COMPILER_OPTIONS
(e.g: generated files with -Wno-warning) but this is less effective and
then we're back at the point where this overrides user flags. It's less
of a concern though.

João Valverde 21d2158a0b CMake: Initial work to install headers for the benefit of plugins
To be continued incrementally to fix gaps and omissions.

If we are willing to reorganize the source tree to have one or two header
include folders this could be simplified considerably.

It would also force developers to give more consideration to API issues,
which is a good thing.

João Valverde e7ef19efc0 autotools: Initial work to install headers for the benefit of plugins
Install public headers required to build plugins for libwireshark (taps and
dissectors).

The source tree is organized to serve the CLI/GUI parts of wireshark.
Plugins are built in tree. This change is intende to allow plugins to be built
out-of-tree but we want to avoid dumping all headers into /usr/include.

To be continued incrementally to fix errors and omissions.
