inserting (long) typedefs to prevent warnings, but in the case of the JS File()
class, actually supporting file lengths > 32-bit.

Added HOST and IP keywords to allow restricted access/privileges to/for
specific remote hostnames or IP addresses (wildcards allowed).
All string-argument type ARS keywords (e.g. SHELL, PROT, etc.) now support .can
style wildcards.
The current remote client is now used for protocol, host, and IP ARS checking,
when available, so this requires passing the client pointer around (which
explains why so many files are touched by this change) and takes care of a
long standing to-do item (the user's 'modem' value was used for the PROT
value checking, which was not always correct).

Constified the arguments.
Created exascii_to_ascii_char().
Created ctrl_a_to_ascii_char().
strip_ctrl() and prep_file_desc() now takes 2 args.
strip_ctrl(), strip_exascii() and prep_file_desc() now strdup() the input
string and if the dest arg is NULL, returns the allocated and modified copy.
sbbs_t::bputs() now handles ^AZ.
Change Ctrl-A code message network exporting:
1. ^AL, ^A<, ^A[, and ^A] are always translated to ASCII equivalents.
2. ^AZ will terminate the message body prematurely if found.
3. Ex-ASCII (CP437) chars will be translated to ASCII equivalents (rather than
'*') for "ASCII Only" subs.
For import, don't allow Ctrl-AP or Ctrl-AL.
For SBBSecho:
Added support for specifying a link's address on the command-line (e.g. for
use with -h).
Mail server now strips Ctrl-A codes from message bodies for sending via POP3
or SMTP.
