This will allow switching to using named pipes.
Split this out as a seperate commit to make changes
easier to follow.

depending on whether the connection is over a socket
or pipe, the read is done differently.
pipes can return -1 when writing 0 bytes, make 0 byte
writes a successful no-op. 0 byte writes falls out
naturally of tcl server code.

pipes have different fd's for in/out. This makes the
code more orthogonal and prepares for adding pipes.

by using ctrl-z instead of line end, multi-line tcl scripts
can be handled.
Testing: send ctrl-z a couple of times to make telnet enter the
mode where it sends ctrl-z unencoded.
Programs that talk to the tcl_server can send ctrl-z to
indicate end of tcl-let to be executed without having
to worry about telnet protocols.

No segmentationfault when sending commands to tcl-server.

Make "usage" messages use the same EBNF as the User's Guide;
no angle brackets. Improve and correct various helptexts.
Specifically for the port commands, clarify that the number
is optional, and omitting it causes the current number to be
displayed.
Don't use "&function"; a function's name is its address.
Remove a couple instances of pointless whitespace; shrink a
few overlong lines.

It's less accepting of signed char ... insisting that e.g. tolower()
not receive one as a parameter.
It's probably good to phase out such usage, given the number of bugs
that lurk in the vicinity (assumptions that char is unsigned), so fix
these even though such usage is actually legal.

By using CALL_COMMAND_HANDLER, parameters can be reordered, added, or
even removed in inherited signatures, without requiring revisiting
all of the various call sites.
OpenOCD doesn't actually *need* to be keeping all TCP ports
active ... creating security issues in some network configs.
Instead, let config file specify e.g. "tcl_port 0" (or gdb_port,
telnet_port) to disable that particular remote access method.

Make startup for the various server ports be quiet, unless
debugging is active: don't emit needless scarey messages.
Update the relevant documentation and its references:
- For these port commands ... cover the default values;
convert to @deffn syntax; include their use outside of
the configuration stage; and alphabetize.
Similar updates to the rest of that small chapter:
- Highlight that there even *IS* a configuration stage, after
which some command functionality is no longer available.
- For GDB commands ... convert to @deffn syntax; alphabetize;
include a missing command (!); add missing helptext (!) for
one non-missing command; update relevant cross-references
and index entries.
