Guy Harris a4c8ebc18b Don't do any Decode As stuff for dissector tables not used with Decode As.
Have all dissector tables have a "supports Decode As" flag, which
defaults to FALSE, and which is set to TRUE if a register_decode_as()
refers to it.

When adding a dissector to a dissector table with a given key, only add
it for Decode As if the dissector table supports it.

For non-FT_STRING dissector tables, always check for multiple entries
for the same protocol with different dissectors, and report an error if
we found them.

This means there's no need for the creator of a dissector table to
specify whether duplicates of that sort should be allowed - we always do
the check when registering something for "Decode As" (in a non-FT_STRING
dissector table), and just don't bother registering anything for "Decode
As" if the dissector table doesn't support "Decode As", so there's no
check done for those dissector tables.

Michael Mann 0bf1cb2342 Add address_to_bytes API.
This will copy an address's "byte format" into a buffer.  The original
intended design is for export_pdu functionality, which tries to do
this "manually" for many address types (and creates undesired dependencies)

The default functionality if a "byte format function" isn't provided
(currently the case for all address types) is a memcpy of the address
data.  Providing "address to byte" functions to aid export PDU
functionality will be provided later.

Michael Mann 1e60d63c8c Create call_data_dissector() to call data dissector.
This saves many dissectors the need to find the data dissector and store a handle to it.

There were also some that were finding it, but not using it.
For others this was the only reason for their handoff function, so it could be eliminated.

Michael Mann 0960ac4dfd Create capture dissector tables.
They are modeled after dissection dissector tables, but for the moment, don't have/need the flexibility.  They are intended to be much simpler/faster than full dissection.
The two most used/needed are "wtap_encap" and "ethertype", so they were the basis of starting to use and test capture dissector table API.  Others may be added in the future.

The "capture dissector" function signature needed a bit of tweeking to handling "claiming" of a packet.
The current application of this is capture functions returning TRUE if they affected a "type" of packet count.  Returning FALSE ends up considering the packet an "other" type.

Michael Mann 56aa05227f Create a way to register "capture" dissectors.
Capture dissectors could be architected like dissection dissectors, with tables and subtables and possibly using tvbs to pass there data instead of raw byte arrays.  This is a first step towards that by refactoring capture_info_packet() to work off of a "capture dissector table"

Registering the capture dissection functions instead of calling them directly also clears up a bunch of dissector header files who sole purpose was providing the capture dissection function definition.

Michael Mann 74541a9596 Don't allow multiple registrations of a protocol in dissector tables.
The target here is the Decode As dialog where protocols have multiple registrations into a dissector table and that shows up as multiple entries in the Decode As dialog list with the same name so users are unsure which "dissector" they are choosing.

The "default" behavior (done in this commit) is to not allow duplicates for a dissector table, whether its part of Decode As or not.  It's just ENFORCED for Decode As.

Guy Harris 90c4cbef19 If it's used by dissectors, it belongs in to_str.h, not to_str-int.h.
Assuming *any* of the routines that generate printable strings should be
thought of as "for internal use by libwireshark routines only, not by
dissectors", the ones that *are* used by dissectors obviously shouldn't
be.  The ability for dissectors to register address types certainly
expands the list of routines they would use.

Move everything used by dissectors from to_str-int.h into to_str.h, and
have dissectors not include to_str-int.h.

(Perhaps we should just get rid of to_str-int.h altogether.)

be moved to epan/dissectors, if they pertain only to stuff exported by a
particular dissector.

Fix Gerald's e-mail address in files we're moving.
