better header sniffing for small files
...
vips__get_bytes() used to fail if the file was too small for the
allocated buffer, which was a problem for svg, since files can be extremely
small.
This change makes vips__get_bytes() return the number of bytes read, so
the is_a testers can work on files smaller than the max header size.

librsvg starts to fail if any single tiles has an axis over 32767
pixels. Break up very wide images to fix this.

Add configure check for zlib with inflateInit2
...
and replace old unused and poorly named FIND_ZIP. The new code prefers
pkgconfig and only falls back to manual detection if needed.
This also prioritizes detected zlib flags and includes to be preferred
over the ones that are added by pkgconfig for libpng, tifflib etc. which
would otherwise have caused the system default zlib to be used.
