Refactor the following code into something that is more clear
and fix signed integer shift, by casting all buf[] elements to
(unsigned int):
unsigned char buf[8];
uint32_t usize;
[...]
else {
usize = buf[4] | buf[5] << 8 |
buf[6] << 16 | buf[7] << 24;
[...]
New version:
usize = buf[4];
usize |= (unsigned int)buf[5] << 8;
usize |= (unsigned int)buf[6] << 16;
usize |= (unsigned int)buf[7] << 24;
Only the "<< 24" part needs explicit cast, but for consistency make the
integer promotion explicit and clear to a code reader.

...
In gunzip(1), treat trailing garbage as a warning and not an error. This
allows scripts to distinguish it between real fatal errors, for instance a
CRC mismatch.
Update manual page for the behavior change.

When reading in the original file name from gzip header, we read
in PATH_MAX + 1 bytes from the file. In r281500, strrchr() is
used to strip possible path portion of the file name to mitigate
a possible attack. Unfortunately, strrchr() expects a buffer
that is NUL-terminated, and since we are processing potentially
untrusted data, we can not assert that be always true.
Solve this by reading in one less byte (now PATH_MAX) and
explicitly terminate the buffer after the read size with NUL.
