260ba0bff1 lib: further adoption of SPDX licensing ID tags.
Mainly focus on files that use BSD 2-Clause license, however the tool I
was using mis-identified many licenses so this was mostly a manual - error
prone - task.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

44a7c65850 Add a file descriptor in struct url for netrc
When using libfetch in an application that drops privileges when fetching
like pkg(8) then user complain because the application does not read anymore
${HOME}/.netrc. Now a caller can prepare a fd to the said file and manually
assign it to the structure.

It is also a first step to allow to capsicumize libfetch applications

72a890ccd7 Add support for HTTP 1.1 If-Modified-Since behavior.
fetch(1) accepts a new argument -i <file> that if specified will cause
the file to be downloaded only if it is more recent than the mtime of
<file>.

libfetch(3) accepts the mtime in the url structure and a flag to
indicate when this behavior is desired.

ec29926e4d 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.

3033318809 Introduce fetchXGet*(), which combine the functionalities of fetchGet*() and

around the other; in all cases, calling fetchGet*() is identical to calling
fetchXGet*() with the second argument set to NULL.

93ce759c73 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.

  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().

  Use 'struct url' instead of 'url_t'.

  Don't use fetchLastErrCode.

 ftp.errors:
  Add categories to all error messages.

 http.c:
  Add fetchStatHTTP().

alphabetical order:

 Makefile:

 common.c: (new file)
  Gather utility functions in this file.

 http.c:
  Remove code that is duplicated elsewhere.

b315880890 Commit a bunch of patches that have been accumulating:
- Fix the README to reflect the new status of the ftp code.
 - Change tons of 'if (xxx < 0)' to 'if (xxx == -1)'
 - Add two new interface functions
 - Fix the Makefile so it actually works (yay!)

Now the manpage is lagging even further behind... :( Next on the todo
list is to clean up the http code.
