The progress bar output function would blindly use the terminal width
without bounds checking. When using a very wide terminal that caused a
buffer overflow and segfault.
We now limit the max bar with to 255 columns, and I simplified the code
to avoid an extra snprintf and buffer.

As commit 5850cc4808 clarifies, libcurl can deliver header lines that
are longer than CURL_MAX_WRITE_SIZE, only body data is limited to that
size. The curl tool has check (when built debug-enabled) that made the
wrong checks and this new test 1205 verifies that larger headers work.
Previously we required that -S/--show-error was used _after_
-s/--silent. This was slightly confusing since we strive to make
arguments as position independent as possible.
Now, you can use them in any order and the result should still be the
same.

Maximum amount of data a header callback is supposed to get in
a single call from libcurl is limited by the lowest value of
CURL_MAX_WRITE_SIZE and CURL_MAX_HTTP_HEADER.
Allow (*curl_write_callback) write callbacks to return
CURL_WRITEFUNC_OUT_OF_MEMORY to properly indicate libcurl of OOM conditions
inside the callback itself.
When we use binary posts and regular ones intermixed on a single command
line, we cannot do strlen() etc on the data to figure out the length
(when inserting '&' and more). We must therefore keep track of the post
data length. Then we also end up setting the libcurl option with the
known size, so that we don't risk that libcurl will do strlen() on the
data.
This has the minor side-effect that --libcurl source codes now always
will use CURLOPT_POSTFIELDSIZE but I don't consider that terribly
damaging.

Reorder handling of fields to match same order as the one given by current
definition order of 'Configurable' struct fields. Fields currently not handled
marked for further inspection.
