Revert Makefile.in changes and remove added tclStringTrim.h header. remove_trim_header

Otherwise, the same changes would be needed by all other Makefile variants as well. 
It's much easier to create a single constant string in tclInt.h, and use this one everywhere.

DKF: No, because the unix makefile is the only one that tracks this info in any case.

JN: OK. My most important remark (sharing of constant strings) is handled in [2191bd8485]. I can very well live with that, so closing this branch.
