ncclimo enable automatice file generation in splitter, fix globbing, other minor fixes

ncclimo/ncremap: Use test -f || test -L (true if file or link) instead of test -f to test for file existance. Verify globbing for input files works.

ncclimo: refactor for inp_aut in timeseries mode, combine annual with monthly filename generation, fix nm_typ=mpas, simplify input determination logic

First cut at automatically generating timeseries filenames. No syntax errors. Names look good but files not found. Filename prefix error.

ncks: nco_chk_???() print full-names only when variable or group is not at root level. Finish nco_chk_bnd().

ncremap: Give v3 algorithm names preference/precedence in listings. Add ncoaave as legitimate map-type directly to nco_rgr.c. Compile by default with -UNCO_ABORT_ON_ERROR not -DNCO_ABORT_ON_ERROR. ncremap tweaks for new algorithm names, e.g., ncoaave, trfv2.

Add MinGW to GNU_TRP and PVM_ARCH types that define WINOS token. Deprecate WIN32 token, use WINOS instead (in pvmgetarch, Makefile, Makefile.old, configure.ac). Determine sls_chr from _MSC_VER and (new) WINOS token instead of (old) WIN32 token.
