Update l3int to mark up 'internal' and 'private' functions

There are a coupld of things here to note:

 - \int_value:w, \int_eval:w, \int_eval_end: were marked as 'internal'
   and so have been moved. Thes show up in a couple of places in TL2012
   (media9 and flexisym) so we may need to contact the appropriate people.
 - The primitive conditionals were marked as internal, but this is not
   consistent with other places so I've simply left them alone at present

Mark 'private' l3keys functions

Mark up internal/private functions in l3luatex, l3prop, l3seq

Quite how to deal with for example \q_prop is not 100% clear:
I have followed what happens with \seq_item:n, which is marked as internal

A number of seq functions pop up elsewhere

The ones in parts of xor are 'hacks', but elsewhere that makes the
functions 'internal' not 'private'

Deal with a small number of places where too many "_" were added

This is all search-and-replace stuff :-)

variable became internal

git-svn-id: svn+ssh://comedy.dante.de/serv/latex-project/svn/experimental/trunk@3829 de43f980-851b-0410-b2f7-c40aca1f87e0
First pass updating l3msg to mark 'private' functions

Two outstanding issues in this
 - What to do about \c_msg_... Are these internal? Should these even
   be constants?
 - \msg_aux_show:Nnx, etc. need better names and also a check on which
   parts are used in other modules (and therefore to be documented)

A couple of "length" => "count" changes.


git-svn-id: svn+ssh://comedy.dante.de/serv/latex-project/svn/experimental/trunk@3831 de43f980-851b-0410-b2f7-c40aca1f87e0
Note that streams are global

Mark up internal/private functions in l3prg

Outstanding here:
 - \group_align_safe_...
 - \scan_align_safe_stop:

In both cases, are these kernel internal or more widely available? For
example, you need \sca_align_safe_stop: for \mode_if... tests inside 
alignments.

Typos.

line_length => line_count, and slight changes to iow_wrap:xnnnN

Namely, the second argument of \iow_wrap:xnnnN, the "run-on text",
is expanded once before formatting the message, rather than at
every line.

As \l_iow_line_length_int is renamed, use that in l3tl-analysis.

Also, rename an auxiliary in xfss.


git-svn-id: svn+ssh://comedy.dante.de/serv/latex-project/svn/experimental/trunk@3837 de43f980-851b-0410-b2f7-c40aca1f87e0
Deprecate \ior(_str)_(g)to:NN to \ior_get(_str):NN.

Those functions are now better aligned with \prop_get:NnN.

Small additions to the documentation.

Mark up 'private' material in l3quark

From the docs, \q_stop, \q_nil, \q_no_value and \q_stop are public

This means that \use_..._delimit_by_q_... logically are public

Scan marks are all internal, but the scan marks themselves will be
renamed when those modules are done

Mark up private functions in l3skip


git-svn-id: svn+ssh://comedy.dante.de/serv/latex-project/svn/experimental/trunk@3841 de43f980-851b-0410-b2f7-c40aca1f87e0
Mark up internal/private functions in l3tl

This includes moving a str function to l3basics

The tl space-stripping code is used in l3clist => 'internal' not
'private': I could do with a bit of a hand with the docs!

The tl-act system is used in tl-act (!), but that could would logically
be addd to l3tl if anywhere, so this looks 'private' to me
