[C]-level users of the [Tcl C API] use to allocate blocks of memory.

** Description **

`ckalloc` is a [C] preprocessor macro which usually expands to '''Tcl_Alloc''',
but the compile-time flag `TCL_MEM_DEBUG` can make it expand to
'''Tcl_DbCkalloc''' call instead. The purpose of this is to support memory
debugging: no change of source files is needed to turn debugging on.

So: If you're new to C, think '''Tcl_Alloc''' (the actual function being
called), but write '''ckalloc''' (the debug-enabled macro) in case you'll
sometime in the future need to debug memory allocation in your code.

Question: Is it a problem if some extensions being used are compiled with
`TCL_MEM_DEBUG and` others are compiled without it?
