Glenn Strauss a69a803e35 [core] try AF_INET after AF_INET6 if use-ipv6
try AF_INET after AF_INET6 if server.use-ipv6 = "enable" and
getaddrinfo() fails EAI_ADDRFAMILY when hints.ai_family is AF_INET6.
(Prefer IPv6 instead of setting hinst.ai_family to AF_UNSPEC since
lighttpd only uses the first address returned)

Glenn Strauss 5ab7944d34 [TLS] release openssl buffers as used (fixes #1265, fixes #1283, #881)
use SSL_MODE_RELEASE_BUFFERS (OpenSSL >= 1.0.0) to free buffers
as they are used, to potentially reduce memory footprint of
idle SSL connections

Glenn Strauss 4eeeb8fc76 [config] server.bsd-accept-filter option
BSD accept() filters

server.bsd-accept-filter = ""           (default)
server.bsd-accept-filter = "httpready"
server.bsd-accept-filter = "dataready"

Note: this is a behavior change from prior versions.
The default is now no additional accept() filter, whereas prior
versions unconditionally enabled "httpready" accept() filter

Additionally, server.defer-accept (Linux) is inherited from global scope
into $SERVER["socket"] blocks

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)

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 292309f88b [core] lighttpd -tt performs preflight startup checks (fixes #411)
lighttpd -t loads config file and performs syntax check
lighttpd -tt (new) performs preflight startup checks,
  including loading and initializing modules, but skipping any
  potentially destructive actions which might affect an already
  running server (separate instance).  These currently include:
  - skipping pidfile modification
  - skipping bind() to network sockets
  - skipping open of error and access logs

Stefan Bühler c033a1966e [core] improve conditional enabling (thx Gwenlliana, #2598)
instead of looping over all config blocks for each conditional var that
gets enabled, enable them all and run over them once.

Right now it seems we actually set all variables at once in normal
config handling (SNI only sets a subset); future modifications
might introduce new variables which are activated at a later stage
(physical path related for example).

Stefan Bühler 6afad87d2e fix buffer, chunk and http_chunk API
* remove unused structs and functions
    (buffer_array, read_buffer)
  * change return type from int to void for many functions,
    as the return value (indicating error/success) was never checked,
    and the function would only fail on programming errors and not on
    invalid input; changed functions to use force_assert instead of
    returning an error.
  * all "len" parameters now are the real size of the memory to be read.
    the length of strings is given always without the terminating 0.
  * the "buffer" struct still counts the terminating 0 in ->used,
    provide buffer_string_length() to get the length of a string in a
    buffer.
    unset config "strings" have used == 0, which is used in some places
    to distinguish unset values from "" (empty string) values.
  * most buffer usages should now use it as string container.
  * optimise some buffer copying by "moving" data to other buffers
  * use (u)intmax_t for generic int-to-string functions
  * remove unused enum values: UNUSED_CHUNK, ENCODING_UNSET
  * converted BUFFER_APPEND_SLASH to inline function (no macro feature
    needed)
  * refactor: create chunkqueue_steal: moving (partial) chunks into another
    queue
  * http_chunk: added separate function to terminate chunked body instead of
    magic handling in http_chunk_append_mem().
    http_chunk_append_* now handle empty chunks, and never terminate the
    chunked body.

Stefan Bühler 6f208cfde1 fix/silence bugs reported by ccc-analyzer (clang)
These should all be non critical:
 * memory leaks on startup in error cases (which lead to
   immediate shutdowns anyway)
 * http_auth/ldap: passing uninitialized "ret" to ldap_err2string
 * sizeof(T) not matching the target pointer in malloc/calloc calls;
   those cases were either:
   * T being the wrong pointer type - shouldn't matter as long as all
     pointers have same size
   * T being larger than the type needed
 * mod_accesslog: direct use after free in cleanup (server shutdown);
   could crash before "clean" shutdown
 * some false positives (mod_compress, mod_expire)
 * assert(srv->config_context->used > 0); - this is always the case,
   as there is always a global config block

Stefan Bühler 05858f6cf2 [ssl] Fix $HTTP["scheme"] conditional, could be "http" for ssl connections if the ssl $SERVER["socket"] conditional was nested (fixes #2501)
con->conf.is_ssl got removed and replaced by:
 * con->conf.ssl_enabled for the config var "ssl.engine" - it is only
   used to determine which server-sockets should use ssl. (usually not
   needed as it is mandatory and enough to set ssl.pemfile anyway)
 * con->srv_socket->is_ssl to detect the actual ssl status of the
   bound socket, which is the same as the ssl status of the connection
 * con->uri.scheme for the actual $HTTP["scheme"] value, also used for
   the CGI "HTTPS=ON" variable. This defaults to "https" if the
   connection uses ssl, but can be changed for example by mod_extforward
   if X-Forwarded-Proto: is set to either "http" or "https" (other values
   are ignored right now)

Also removed the broken srv_socket->is_proxy_ssl as it was a connection
value in a server_socket struct...
