When saving preferences the strings in string lists must not be
escaped with g_strescape() because this will destroy UTF-8 characters.
Because this strings only should use printable characters we manually
escape quote and backslash, and skip non-printable.

Move "struct preference" into prefs.c, essentially creating a "private"
structure to handle preferences. The 2 motivating factors were:
1. Better memory management so that clients/users of API don't have to worry
about it.
2. Hide the ugliness of the union stuff and make it transparent to the API.
A few bugs related to preference <-> Decode As integration were fixed
while in the neighborhood.

This patch introduces new APIs to allow dissectors to have a preference for
a (TCP) port, but the underlying data is actually part of Decode As functionality.
For now the APIs are intentionally separate from the regular APIs that register a
dissector within a dissector table. It may be possible to eventually combine the
two so that all dissectors that register with a dissector table have an opportunity
to "automatically" have a preference to adjust the "table value" through the
preferences dialog.
The tcp.port dissector table was used as the guinea pig. This will eventually be
expanded to other dissector tables as well (most notably UDP ports). Some
dissectors that "shared" a TCP/UDP port preference were also converted. It also
removed the need for some preference callback functions (mostly when the callback
function was the proto_reg_handoff function) so there is cleanup around that.
Dissectors that has a port preference whose default was 0 were switched to using
the dissector_add_for_decode_as_with_preference API rather than dissector_add_uint_with_preference
Also added comments for TCP ports used that aren't IANA registered.

Always initialize prefs.col_list in pre_init_prefs.
When switching to a profile without a saved 'preferences' file we
have to initialize prefs.col_list to default values to avoid reusing
settings from the profile we leave.
This was introduced in 5012cf84e6
Emit columnsChanged() before preferencesChanged().
This because columnsChanged() rebuilds cap_file_->cinfo which is used
in preferencesChanged() to align columns (and possible other actions).
Doing this in the wrong order will give an inconsistency and a
heap-buffer-overflow if having different number of columns.

Quick hack fix for bug 11275.
The longer fix I am still thinking about, but it goes something like this: we
have a terribly confusing dependency graph in ordering our various preferences,
so it's fragile and needs refactoring.
1. We must call epan_init before we read the preferences files, since dissectors
register many preferences.
2. We must call pre_init_prefs before we call prefs_register_modules, since that
inits the default values of the "global" preferences structure. `init_prefs()`
handles this normally.
3. We must call epan_init before we call init_prefs since init_prefs depends on
UATs being initialized (which is something epan_init does).
4. We must call prefs_register_modules before we call epan_init since that
generates the `protocols` subtree which is needed for registering
dissector-specific preferences.
The above graph has a cycle, which I *think* can be solved by splitting
prefs_register_modules?
