Using fmemopen here wasn't necessary, since memcpy could have been used
with way lower overhead. We don't use a dedicated function, because
turning a data field into a string is an inefficient operation and
shouldn't be encouraged.
Also don't initialize data when it's declared, it isn't necessary.
- use less intermediate variables
- assert that archive_read_new managed to allocate memory for itself:
not ideal, but if we ever want to move from assertions it shows us
where we need to change things
- use libarchive's archive_error_string for better error messages

Both CFLAGS and LDFLAGS need to be passed during linkage as CFLAGS may
contain things that influence linkage (e.g. ssp_nonshared may be
necessary to link when using strong stack protector).
Pointed out by q66.
Closes: #330 [via git-merge-pr]
The HTTP_REDIRECT() macro already included this case, but the
switch-case with the return value of http_get_reply(conn) didn't. This
made it so that a server returning HTTP_TEMP_REDIRECT (307) would
generate a failure, unless libfetch was used in verbose mode, in which
case the headers would be parsed (in order to report errors), then the
'Location' header would be found and a new connection would be made.
Fixes#348
Initializing structs with '{}' is supported on most compilers, but not
defined in the standard. The correct initializer for this is '{0}'.
Spotted with cproc.
The width of unsigned long matching the width of a pointer isn't
guaranteed by any standard, though it is a requirement of the Linux
syscall API. Using uintptr_t directly is always correct.
