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. Assisted-by: Jay Satiro Closes #17253
