skip building separate modules for built-in modules

Small modules with minimal dependencies are now built-in to lighttpd.
All 12 of these modules have a memory footprint that is approximately
the same as 1 single module built as a .dll due to mandatory minimum
binary sections and memory page sizes (4k each).

[core] build core modules into lighttpd executable

In dynamic build of lighttpd, at runtime each loaded lighttpd module .so
takes at least (5) 4k memory pages on x86_64. That is at least 20k per
module. Building 10 small core modules into lighttpd adds less than 16k
.text total, and adding mod_fastcgi and mod_scgi totals less than 20k
.text (plus an extra 4k .rodata page). The end result is that memory
usage is almost the same if only mod_staticfile is used, and 20k or so
is saved for each additional module used if among those built into
lighttpd executable.

For now, the standalone .so modules continue to be built, even though
not used by the lighttpd executable. This is done in order to give
distros time to update packaging scripts and transition to not
expecting the builtin module artifacts to be produced or installed as
part of the distro lighttpd package.

[multiple] remove deprecated modules

remove deprecated modules:
mod_evasive
mod_secdownload
mod_uploadprogress
mod_usertrack

These scheduled lighttpd behavior changes have been announced over
the past year:

* Continue gradual deprecation of "mini-application" lighttpd modules
for which mod_magnet lua implementations are better and more flexible.
Please post on lighttpd forums to share feedback if you use these modules.
Forums: https://redmine.lighttpd.net/projects/lighttpd/boards

* Deprecated: mod_evasive has been removed.
mod_evasive can be replaced by mod_magnet and a few lines of lua:

* Deprecated: mod_secdownload has been removed.
mod_secdownload can be replaced by mod_magnet and a few lines of lua:
Replacement: https://wiki.lighttpd.net/ModMagnetExamples#lua-mod_secdownload
mod_secdownload historically uses insecure MD5 though SHA1, SHA256 available

* Deprecated: mod_uploadprogress has been removed.
mod_uploadprogress can be replaced by mod_magnet and a few lines of lua:
Replacement: https://wiki.lighttpd.net/ModMagnetExamples#lua-mod_uploadprogress

* Deprecated: mod_usertrack has been removed.
