curlx: move into to curlx/ 
Move curlx_ functions into its own subdir.

The idea is to use the curlx_ prefix proper on these functions, and use
these same function names both in tool, lib and test suite source code.
Stop the previous special #define setup for curlx_ names.

The printf defines are now done for the library alone. Tests no longer
use the printf defines. The tool code sets its own defines. The printf
functions are not curlx, they are publicly available.

The strcase defines are not curlx_ functions and should not be used by
tool or server code.

dynbuf, warnless, base64, strparse, timeval, timediff are now proper
curlx functions.

When libcurl is built statically, the functions from the library can be
used as-is. The key is then that the functions must work as-is, without
having to be recompiled for use in tool/tests. This avoids symbol
collisions - when libcurl is built statically, we use those functions
directly when building the tool/tests. When libcurl is shared, we
build/link them separately for the tool/tests.

** Macros for test source code readability/maintainability.
**
** All of the following macros require that an int data type 'res' variable
** exists in scope where macro is used, and that it has been initialized to
** zero before the macro is used.
**
** exe_* and chk_* macros are helper macros not intended to be used from
** outside of this header file. Arguments 'Y' and 'Z' of these represent
** source code file and line number, while Arguments 'A', 'B', etc, are
** the arguments used to actually call a libcurl function.
**
** All easy_* and multi_* macros call a libcurl function and evaluate if
** the function has succeeded or failed. When the function succeeds 'res'
** variable is not set nor cleared and program continues normal flow. On
** the other hand if function fails 'res' variable is set and a jump to
** label 'test_cleanup' is performed.
**
** Every easy_* and multi_* macros have a res_easy_* and res_multi_* macro
** counterpart that operates in the same way with the exception that no
** jump takes place in case of failure. res_easy_* and res_multi_* macros
** should be immediately followed by checking if 'res' variable has been
** set.
**
** 'res' variable when set will hold a CURLcode, CURLMcode, or any of the
** TEST_ERR_* values defined above. It is advisable to return this value
** as test result.
