Bumped version numbers, and cleaned up trailing whitespace from some files.

Test suite exercises -c now.
txr.c (txr_main): If the script specified with -c is not terminated
by a newline, just add a newline. On the shell command line, it's a
nuisance to have to add the extra line before closing the quote.
It's also awkward in scripting, because the shell (or at
least Bash 3.0) does not produce a final terminating newline in command
substitution syntax like -c "$(cat file)". The last newline in
the file is trimmed, and has to be explicitly added in the script
itself, which is wrong in the case when the file is empty.

semantics on the input stream to wide character input.
Also, reading a query the command line (-c) must
read bytes from a UTF-8 encoding of the string.
We introduce a new get_byte function which can extract bytes
from streams which provide it.

use wide character functions so that there is no illicit
mixing. (But the goal is to replace this usage with txr streams).

so that the C library streams do the encoding. Once the program
is weaned from C library wide character stream I/O, this can go away.

This is incomplete. There are too many dependencies on
wide character support from the C stream I/O library,
and implicit use of some encoding which may not be UTF-8.
The regex code does not handle wide characters properly.
Character type is still int in some places, rather than wchar_t.
Test suite passes though.

termination. Pipe and stdio streams have an extra description field
so they are printed in a readable way.

Lazy strings implemented, incompletely.
Changed string function to implicitly strdup; non-strdup
version changed to string_own. Fixed wrong uses of strdup
rather than chk_strdup.
Functions added to regex module to provide regex matching
as a state machine to which characters are fed.
