c42cb9d906 Add and document support for a FETCH_BIND_ADDRESS environment variable
specifying a local address to bind sockets to.  Caveat: lightly tested.

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.

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.

e19e6098b3 Reindent, and add parentheses to return statements. Some functions in
ftp.c and http.c now have exceedingly long lines due to deep nesting;
this will be corrected by reorganizing the code in a later revision.

f573a5fc94 Tons of type, style and warning fixes that have been rotting in my tree for
ages - some of which wouldn't be necessary if gcc wasn't broken or TPTB were
willing to do something (-fno-builtin) about it.

d8acd8dc5c Second of a series of cleanups to libfetch.
This commit introduces the following features:

 a) the fetchStat*() functions, which return meta-information for a
    document, such as size, modification time, etc.

 b) the use of the com_err(3) facilities to report errors.

It also fixes a bunch of style bugs and a few logic bugs and somewhat
improves the man page.

Changed files, in alphabetical order:

 Makefile:
  Don't generate macros in {ftp,http}err.c.

  Generate category fields for the error message lists.

  Compile the error table.

  Install fetch_err.h along with fetch.h.

 common.c:
  Remove the _netdb_errstring() macro, and add FETCH_ERR_NETDB to the
  error code in the _netdb_seterr() macro.

  Add categories to the _netdb_errlist table.

  Report errors through the Common Error library.

 common.h:
  Add the DEBUG macros.

  Add prototype for fetchConnect().

  Remove the prototype for _fetch_errstring(), which is local to common.c

  Add a categroy field to struct fetcherr, and define constants for
  error categories.

  Define macros for _{url,netdb,ftp,http}_seterr().

 errors.et: (new file)
  List error categories.

 fetch.3:
  Document the fetchStat*() functions.

  Move the "unimplemented functionality" comments from NOTES to BUGS.

  Document that applications which use libfetch must also use
  libcom_err, and list existing error codes.

  Undocument fetchLastErr{Code,String}.

  Remove the (empty) DIAGNOSTICS section.

  Mention Eugene Skepner in the AUTHORS section.

 fetch.c:
  Move the DEBUG macros to common.c

  Add fetchStat() and fetchStatURL().

  Generate error messages for URL parser errors, and fix a minor bug
  in the parser.

  Use 'struct url' instead of 'url_t'.

  Remove fetchLastErr{Code,String}.

 fetch.h:
  Use 'struct url' instead of 'url_t', and remove the typedef.

  Define struct url_stat (used by fetchStat()).

  Add prototypes for fetchStat*().

  Remove the declarations for fetchLastErr{Code,String}.

  Include fetch_err.h.

 fetch_err.et: (new file)
  Error table for libfetch.

 file.c:
  Add fetchStatFile().

  Use 'struct url' instead of 'url_t'.

 ftp.c:
  Add fetchStatFTP().
