Message:

Renaming fits->compression to fits->compConvention to distinguish between compression and compresion convention. Reworking psFitsMoveExtName, essentially using p_psFitsMoveExtName_UserKey as psFitsMoveExtName: Files compressed with cfitsio's 'imcopy' program may have multiple EXTNAME keywords, with the first set to COMPRESSED_IMAGE. However, fits_movnam_hdu won't find the second (proper) value of EXTNAME, and so can fail to find a perfectly legitimate extension, simply because imcopy does something silly. However, we really want to be able to read these files (MegaCam data are shipped as imcopy-compressed images). Therefore, we implement our own version of moving to an extension specified by name. The pure cfitsio version (what was originally in psFitsMoveExtName) is used if 'compConvention' handling is turned off in the psFits structure.
