- fix "gzip -t" to not output anything by default. PR#25507
...
- fix any decompression on corrupted gzip files. PR#25508
- ask to overwrite files if we have a tty, rather than failing the
operation. PR#25509.
- clean up maybe_err()/maybe_warn(): use maybe_err() only for fatal
errors. maybe_warn() is for processing errors. this allows
"gzip -d file1.gz file2.gz" to decompress file2.gz even if file1.gz
is corrupted, etc.
- change the internal compressor/decompressor API to return "-1" on
failure, not 0. this allows for 0-sized files to be decompressed
correctly.

WARNS=3: add some const poisoning, and sort out local variable

definitions shadowing other variables.
Pass storage for file names into the file_compress and file_uncompress
functions, so that we don't run the risk of leaking memory. Remove a global
variable that's no longer needed.

Fix a reference to stale storage on the stack - malloc the new file
...
name when gunzip'ing via strdup(3). Fixes a bug whereby the new
filename would appear as gibberish when verbosely gunzipping.
Fix an off-by-one error when allocating the filename with added suffix,
and properly NUL-terminate the new filename.
It's NULL, not 0, in char * assignments - there are some still to do here.

significantly rototill. don't use the high-level gzio functions
...
anymore, use the low-level inflate()/deflate() directly. this
allows support file-type detection on stdin; now can decompress
.Z and .bz2 files fed to stdin (fixes PR#25192) additionally it
makes -v work with stdin or stdout (fixes PR#25215.)
(with these changes, we no longer need gzopenfull(3) in libz.)
