Snapshot of SVN 5421

[Joseph Wright]

Hello all,

A snapshot of the LaTeX3 code has been submitted to CTAN. Key changes:

- Change in treatment of juxtaposition in l3fp: now simply
inserts "*" and thus has same precedence as explicit "*" or
"/" (this is a breaking change as discussed previously)
- Produce 'string-like' output as standard in l3regex
replacements: "\ " in replacement text has catcode 10

- New single l3str module in kernel for 'stable' \str_...
functions
- New \str_fold_case:n function for Unicode (UTF-8) case
folding
- Functions moved to 'stable' status: \clist_const:Nn,
\<thing>_item:Nn, \clist_set_from_seq:NN,
\seq_set_from_clist:NN, \seq_reverse:N
- New \dim_to_decimal:n and related function to replace
experimental \dim_strip_pt:n, etc.
- New experimental expandable Unicode case changing functions
\tl_lower_case:n, \tl_upper_case:n, \tl_mixed_case:n.
- New experimental \box_resize_to_ht:Nn and
\box_resize_to_wd_and_ht:Nn as per user request

- Bug fix for "\c{...}" construct in l3regex
- Bug fix for logarithms in l3fp

Please give it around 48 h for the new code to propagate around CTAN.
