Glenn Strauss 1ca52fdce3 build with libressl
libressl defines SSL_OP_NO_SSLv2 and SSL_OP_NO_SSLv3 as 0x0
  (thx Christian Heckendorf)

libressl matches ERR_remove_thread_state() signature from openssl 1.0.2
  (libressl pretends that libressl is openssl version 2.0.0,
   but openssl 1.1.0 changes signature of ERR_remove_thread_state())

libressl does not yet provide compatibility interfaces for the new
  prototypes introduced in openssl 1.1.0, including
  DH_set0_pqg() and DH_set_length()

remove OPENSSL_NO_KRB5 from build config (added in 5fab991b in 2005)
  (define USE_OPENSSL_KERBEROS if required)
  (Note: OPENSSL_NO_KRB5 removed in openssl 1.1.0)

  "add RFC-compliant LOCK support to mod_webdav"  (still not compliant)
  https://redmine.lighttpd.net/issues/1818

Note: this has not been tested whether or not mod_webdav works with git
The (highly) recommended method to support git via HTTP is to use
git-http-backend via CGI.  gitolite and gitosis provide other good
alternative ways to access git.

This patch does result in more WebDAV 'Litmus' tests passing, even
though mod_webdav still pretends to implement "If" conditional locking,
granting locks to all requestors and not strictly enforcing locks.

Glenn Strauss e0115208ec [mod_webdav] map COPY/MOVE Destination to aliases (fixes #1787)
attempt to remap COPY/MOVE Destination to aliased physical paths
by finding common URI prefix between request URI and Destination
and finding how that part of the request URI was mapped to a
physical path.

This will work if the aliased physical path is above the webdav root.
It is not a good idea to remap physical paths within a webdav root.

Note: webdav paths and webdav properties are managed by mod_webdav,
      so do not modify paths externally or else undefined behavior
      or corruption may occur

Glenn Strauss 1812f5541a [core] lighttpd -1 handles single request on stdin socket (fixes #1584)
(e.g. when called from xinetd)

Note: lighttpd is designed as a high performance, long-running server,
not a one-shot executable.  This one-shot mode of operation has not been
tuned for performance.  lighttpd server start-up and initialization aims
for correctness, not speed.  If using this one-shot mode as part of fork
and exec from xinetd, then performance is already not of high concern.

Glenn Strauss 06b87dee34 [core] cmd line opt to shutdown after idle time limit (fixes #2696)
-i <secs>  graceful shutdown after <secs> of inactivity

Option might be used with applications such as git instaweb.
While git instaweb does have command line options of its own
to [start,stop,restart], some may find it convenient to configure
git instaweb to start lighttpd with a default idle time limit,
after which lighttpd will gracefully shut itself down without
any further action from the user.

Glenn Strauss 8e3c6bf754 fallback to lseek()/read() if mmap() fails (#fixes 2666)
fallback to lseek()/read() if mmap() fails (#fixes 2666)
e.g. when mmap() is used on lighttpd-controlled temporary files
used POST request body (mod_cgi) and PUT file upload (mod_webdav)

replace use of stream_open() on potentially untrusted files
(protect against SIGBUS if a file is modified while map is read)
Note: stream.[ch] may be removed in a future release
For now, stream.[ch] will read entire file into memory if mmap fails
and so it should only be used on trusted files, e.g. config files.

http_auth basic and digest files are typically small and so buffered
stdio fopen(), fgets(), fclose() will likely be approximately as fast
as mmap.

mod_dirlisting header and readme files are typically small and so
open(), read(), close() will typically be approximately as fast as mmap

mod_ssi will likely be much faster, now buffering SSI page construction
rather than a potentially huge number of file open() calls, one for each
tiny chunk of text between SSI directives.

mod_webdav COPY and MOVE may be slower due to removal of mmap, but are
now more resilient to partial writes.

Glenn Strauss b9940f9856 [mod_fastcgi] use http_response_xsendfile() (fixes #799, fixes #851, fixes #2017, fixes #2076)
handle X-Sendfile and X-LIGHTTPD-send-file w/ http_response_xsendfile()
  if host is configured ( "x-sendfile" = "enable" )

Note: X-Sendfile path is url-decoded for consistency, like X-Sendfile2
      (response headers should be url-encoded to avoid tripping over
       chars allowed in filesystem but which might change response
       header parsing semantics)

Note: deprecated: "allow-x-send-file";         use "x-sendfile"
Note: deprecated: X-LIGHTTPD-send-file header; use X-Sendfile header
Note: deprecated: X-Sendfile2 header;          use X-Sendfile header
For now, X-Sendfile2 is still handled internally by mod_fastcgi.

Since http_response_send_file() supports HTTP Range requests,
X-Sendfile2 is effectively obsolete.  However, any code, e.g. PHP,
currently using X-Sendfile2 is probably manually generating 206 Partial
Content status and Range response headers.  A future version of lighttpd
might *remove* X-Sendfile2.  Existing code should be converted to use
X-Sendfile, which is easily done by removing all the special logic
around using X-Sendfile2, since the 206 Partial Content status and Range
response headers are handled in http_response_send_file().

Glenn Strauss dbdab5dbc9 [core] server.error-handler new directive for error pages (fixes #2702)
server.error-handler preserves HTTP status error code when error page
is static, and allows dynamic handlers to change HTTP status code
when error page is provided by dynamic handler.  server.error-handler
intercepts all HTTP status codes >= 400 except when the content is
generated by a dynamic handler (cgi, ssi, fastcgi, scgi, proxy, lua).
The request method is unconditionally changed to GET for the request
to service the error handler, and the original request method is
later restored (for logging purposes).  request body from the
original request, if present, is discarded.

server.error-handler is somewhat similar to server.error-handler-404,
but server.error-handler-404 is now deprecated, intercepts only 404
and 403 HTTP status codes, and returns 200 OK for static error pages,
a source of confusion for some admins.  On the other hand, the new
server.error-handler, when set, will intercept all HTTP status error
codes >= 400.  server.error-handler takes precedence over
server.error-handler-404 when both are set.

NOTE: a major difference between server.error-handler and the
now-deprecated server.error-handler-404 is that the values of the
non-standard CGI environment variables REQUEST_URI and REDIRECT_URI
have been swapped.  Since REDIRECT_STATUS is the original HTTP
status code, REDIRECT_URI is now the original request, and REQUEST_URI
is the current request (e.g. the URI/URL to the error handler).
The prior behavior -- which reversed REQUEST_URI and REDIRECT_URI values
from those described above -- is preserved for server.error-handler-404.

Additionally, REDIRECT_STATUS is now available to mod_magnet, which
continues to have access to request.uri and request.orig_uri.
