fc2841a92f Fix one-byte buffer overflow: NUL gets written to the buffer, but isn't
counted in the width specification in scanf.

This is not a security problem, since this function is only used to
parse a user's configuration file.

62a2681c93 Add support for the NO_PROXY / no_proxy environment variable as used by
lynx, curl etc.  Note that this patch differs significantly from that
in the PR, as the submitter refined it after submitting the PR.

32a4a82829 Fix an off-by-one error (> where >= should have been used) which caused
_fetch_writev() to incorrectly report EPIPE in certain cases.

Also fix a number of const warnings by using __DECONST(), plus a signed /
unsigned comparison by casting the rhs to ssize_t.

1a5424b137 Slight amendment to rev 1.34: instead of considering any short read an
error, only report an error if no data was read at all (unless len was
0 to start with).  Otherwise, the final read of practically any transfer
will end in a fatal error.

2761348f78 Introduce _fetch_writev(), which is the conn_t version of writev(2). In
the SSL case, it is no different from the old _fetch_write(), but in the
non-SSL case it uses writev(2) to send the entire vector as a single
packet (provided it can fit in one packet).  Implement _fetch_write()
and _fetch_putln() in terms of _fetch_writev().

This should improve performance in the non-SSL case (by reducing protocol
overhead) and solve the problem where too-smart-for-their-own-good
firewalls reject FTP packets that do not end in CRLF.

e24f60e74f Back out the previous commit, and fix the bug rather than try to hide its
symptoms: make timeouts and short transfers fatal, and set errno to an
appropriate value (ETIMEDOUT for a timeout, EPIPE for a short transfer).

9601e333a8 Wrap everything in struct connection, and enforce timeouts everywhere
(except for DNS operations).  Always use funopen() for HTTP, to support
both timeouts and SSL.

dea29ca1d5 First step towards SSL support: wrap connections in a 'struct connection'
which contains the socket descriptor, the input buffer and (yet unused)
SSL state variables.  This has the neat side effect of greatly improving
reentrance (though we're not *quite* there yet) and opening the door to
HTTP connection caching.

This commit is inspired by email conversations with and patches from
Henry Whincup <henry@techiebod.com> last fall.

a1bb3f482a Introduce the (undocumented) variable fetchRestartCalls, which controls whether
or not interrupted system calls will be restarted. This fixes a bug where
fetch(1) would hang (potentially forever) if a server stopped responding,
because the signal handler would absorb the user's efforts to interrupt the
transfer.
