lzlib: 'make-lzip-input-port' better handles end of decompression.
...
Suggested by Pierre Neidhardt <mail@ambrevar.xyz>.
* guix/lzlib.scm (lzread!): Call 'lz-decompress-finish' when
'feed-decoder!' returns EOF. Call 'lz-decompress-finished?' to
determine end of compression.

lzlib: 'lzread!' never returns more than it was asked for.
...
Fixes a bug whereby 'lzread!' could return more than COUNT.
* guix/lzlib.scm (lzread!): Rewrite in a semi-functional style.

lzlib: Adjust 'lz-compress-read' docstring.

guix: Simplify and robustify lzread!.
...
* guix/lzlib.scm (lzread!): Do it.
Previously lzread! would fail if COUNT was bigger
than (lz-decompress-write-size). This is possible if a previous call to
lzread! didn't empty the LZ_decompress input buffer (e.g. BV was too small to
fit all the data).
