Although removal of AM_PROG_CC_C_O in f107bac8 requires automake 1.14
to provide the same functionality in AC_PROG_CC, any widely used,
modern compiler supports cc -c -o. Reducing the minimum required
automake version avoids the current need for Centos 7 maintainers
to patch configure.ac in order to build binary packages.
allow sendfile() in cross-compile if sys/sendfile.h header detected
and sendfile() symbol detected (e.g. in libc)
If sendfile() is present but always returns ENOSYS, lighttpd will
be slightly less efficient, but will fall back to writev() or write()
User should explicitly set server.network-backend = "writev" in
lighttpd.conf on systems with broken sendfile()

- AC_USE_SYSTEM_EXTENSIONS requires autoconf 2.60; using it replaces
AC_AIX, AC_ISC_POSIX, AC_MINIX and -D__EXTENSIONS__
- require at least automake 1.12 to remove hack for serial-tests
- automake 1.12 is from 2012, automake 1.14 from 2013
- automake 1.14 allows us to drop AM_PROG_CC_C_O
- we don't use $LN_S, drop AC_PROG_LN_S
- silent-rules replaces AM_SILENT_RULES

decodes websockets and passes body back and forth from backend
(body could be known protocol such as JSON, or any custom protocol)
originally based off https://github.com/nori0428/mod_websocket
autotools now use AC_PROG_CC_STDC macro instead of -std=gnu99.
The default in current modern gcc compilers is -std=gnu11
(Note: src/CMakeLists.txt and SConstruct still specify -std=gnu99)
add doc/initscripts.txt with description of lighttpd signal handling
and links to the initscripts of various operating system distros
remove doc/initscripts/*

Lack of pipe2() on relic Unix as well as missing on Mac OSX is likely
one reason why threaded web servers such as nginx choose not to support
CGI except via an external service to the process. Without pipe2(),
race conditions exist and it is not safe for a threaded server to use
pipe() and fork() when the server also does not want to potentially leak
open file descriptors to various unrelated CGI scripts.
- "autoreconf --force --install" should be enough to get autobuild
running, manual cp / running ./autogen.sh should not be required
- reorganize files laters, e.g. scripts/{cmake,m4}
- include ax_prog_cc_for_build.m4 manually in configure.ac as it is not
automatically loaded if it is not in m4/
[mod_deflate] skip deflate if 1 min loadavg too high
deflate.max-loadavg = "3.50" # express value as string of float num
[mod_compress] skip compression if 1 min loadavg too high
compress.max-loadavg = "3.50" # express value as string of float num
Feature available on BSD-like systems which have getloadavg() in libc
Note: load average calculations are different on different operating
systems and different types of system loads, so there is no value that
can be recommended for one-size-fits-all.
