João Valverde d0a91b27f2 plugins: config.h must not be included by public headers
For a sane plugin build environment. Include config.h as the first
header in the .c file instead.

Fix by moving required compiler attribute macros to a new
"ws_attributes.h" API header.

João Valverde 7466880e8a Parse enterprise-numbers at run time
"enterprise-numbers" is converted to tab-separated values and renamed
"enterprises". Unused fields are stripped.

PENs are stored in a hash table loaded at run-time.

User "enterprises" file is loaded from the personal config dir.

Misc make-sminmpec.pl improvements and fixes.
Note: names of type "Entity (formerly ...)" have the formerly part commented out for a cleaner output.

Guy Harris 913f9fb353 Rename BASE_VALS_NO_UNKNOWN to BASE_SPECIAL_VALS.
It makes it a bit clearer what its purpose is - to allow a value_string
to be used for numeric rather than enumerated fields, giving certain
values of the field a special meaning.

Change the explanation in the documentation to match as well.

Guy Harris 2c44a7f930 Clean up handling of enabled/disabled protocols/heuristic dissectors.
Add a "report a warning message" routine to the "report_err" code in
libwsutil, and rename files and routines appropriately, as they don't
only handle errors any more.

Have a routine read_enabled_and_disabled_protos() that reads all the
files that enable or disable protocols or heuristic dissectors, enables
and disables them based on the contents of those files, and reports
errors itself (as warnings) using the new "report a warning message"
routine.  Fix that error reporting to report separately on the disabled
protocols, enabled protocols, and heuristic dissectors files.

Have a routine to set up the enabled and disabled protocols and
heuristic dissectors from the command-line arguments, so it's done the
same way in all programs.

If we try to enable or disable an unknown heuristic dissector via a
command-line argument, report an error.

Update a bunch of comments.

Update the name of disabled_protos_cleanup(), as it cleans up
information for disabled *and* enabled protocols and for heuristic
dissectors.

Support the command-line flags to enable and disable protocols and
heuristic dissectors in tfshark.

were being dissected incorrectly.

For the encodings with seconds and 1/2^32s of a second, don't
arbitrarily give only microsecond resolution; 2^32 is greater than 1
million, and, in fact, at least some NTP RFCs explicitly talk about time
resolution greater than 1 microsecond.

Update references in the RELOAD dissector to reflect the documents in
question having been updated and published as RFCs.

Jeff Morriss 3a590217ac Change how dissectors do late-field-registration to avoid a double-registration
assertion.

If a dissector forces registration of fields during dissection it needs to do
so in a way that clears the prefix registration.  Otherwise epan will call the
registration routine a 2nd time (which will cause us to assert out) if a user
types a display filter (with the dissector's prefix) that doesn't exist.

Update the proto_register_prefix() comments to reflect this.

It requires some "extra work" to get it to work properly.  Despite
documenting it, some previous use cases didn't do the extra work.
Let's just see how we get by without it.

Peter Wu 57b2a84f3d Use a single WS_NORETURN macro
Having to define two macros for marking a function as never returning
seems a bit redundant. Merge the MSVC and GCC-like attributes into a
single WS_NORETURN.

Tested with Clang 3.7.1, GCC 4.4.7 and even GCC 4.1.2 using this small
program (-Wall -Wextra, the first two generate warnings for
uninitialized variables, the last one compiles without warnings):

    #include <stdlib.h>
    __attribute__((noreturn)) void foo() { exit(1); }
    __attribute__((noreturn)) void bar();
    void bar() { exit(1); }
    int main() {
      int j, i;
      if (i) { bar(); return j; }
      foo();
      return j;
    }

Jeff Morriss fda0bafeb8 Ensure our fields are registered before starting dissection--even when !tree.
(The check to ensure the delayed field registration had been done was still
wrapped inside an if(tree) but a bunch of proto_add_*()'s had been pulled out
from under if(tree)'s thus causing some hf's to be used before registered.)

Also simplify the code to ensure the fields are registered since we're doing it
potentially many times per frame: do an integer comparison rather than looking
up an hf by name.

Add a note to the docs for proto_register_prefix() to make it clear that the
initializer routine may not be called before the dissector is asked to dissect
something.

Guy Harris b9fb2ceb88 Add heuristic dissectors for the variable part of COTP CR and CC PDUs.
Add tables for heuristic dissectors, and add dissectors for the stuff
Microsoft puts there for RDP; they're violating the COTP spec, but I
guess they're stuck because they're using TP0, which doesn't support
user data.

While we're at it, add variants of proto_tree_add_bitmask() and
proto_tree_add_bitmask_flags() that return the bitmask, for use by
callers.

A side-effect of the change is that the proto_tree_add_bitmask routines
no longer treat the encoding as a Boolean, so we have to pass
ENC_LITTLE_ENDIAN or ENC_BIG_ENDIAN, not just some non-zero or zero
value.  Do so.

Rename ositp_decode_CC() to ositp_decode_CR_CC(), to note that it
decodes both CR and CC PDUs.

Kevin Bracey 9eda2fa063 Set width of hex output according to bitmask
Output from BASE_HEX et al has always been zero-padded to according to
the field type - 8 digits for FT_UINT32, etc.

When the field has a bitmask, this is definitely not appropriate - the
field type is used to indicate the size of the bitfield container, and
tells us nothing about the size of this field.

Instead, determine the actual size of the field by inspecting the
bitmask, and output the corresponding number of hex digits.

Guy Harris c67c6e8f30 Add routines to add an item and return the item's real length.
proto_item_get_len() is *not* guaranteed to return a correct value.
Even if there's a non-null tree item, it might be pointing to a "faked"
item; it really shouldn't be used.

So add proto_tree_add_item_ret_length() and
proto_tree_add_item_new_ret_length(), which calculate the real length
themselves and return it through a pointer.

Fix as many places as we straightforwardly can to use them rather than
to use proto_item_get_len().  (There's a Lua API for
proto_item_get_len(), so we keep it around, but we should add Lua APIs
for the new routines, and deprecate the old API.)

Fix ptvcursor_add() to do the same thing that
proto_tree_add_item_ret_length() and
proto_tree_add_item_new_ret_length() do.

Split the TRY_TO_FAKE_THIS_ITEM macros into a macro to check for the
tree being null and to try to fake the item.  We don't always use the
former macro, as we might need to do more than just return NULL if the
incoming tree is null (for example, calculating the item's real length
and using it...).

new_field_info() never returns NULL; remove checks for it.  The check
for a null tree is done before the calls to new_field_info().
