This makes the build tree more organized, which is good for adding new
stuff. Now, it's useful for example for adding manual pages in man3/,
but it may be useful in the future for example for extending the build
system to run linters (e.g., clang-tidy(1), Clang analyzer, ...) on the
C source code.
Previously, the build tree was quite flat, and looked like this (after
`./configure && make`):
$ tree -I src build
build
├── Makefile
├── autoconf.data
├── autoconf.err
├── echo
├── libnxt.a
├── nxt_auto_config.h
├── nxt_version.h
├── unitd
└── unitd.8
1 directory, 9 files
And after this patch, it looks like this:
$ tree -I src build
build
├── Makefile
├── autoconf.data
├── autoconf.err
├── bin
│ └── echo
├── include
│ ├── nxt_auto_config.h
│ └── nxt_version.h
├── lib
│ ├── libnxt.a
│ └── unit
│ └── modules
├── sbin
│ └── unitd
├── share
│ └── man
│ └── man8
│ └── unitd.8
└── var
├── lib
│ └── unit
├── log
│ └── unit
└── run
└── unit
17 directories, 9 files
It also solves one issue introduced in
5a37171f73 ("Added default values for pathnames."). Before that
commit, it was possible to run unitd from the build system
(`./build/unitd`). Now, since it expects files in a very specific
location, that has been broken. By having a directory structure that
mirrors the installation, it's possible to trick it to believe it's
installed, and run it from there:
$ ./configure --prefix=./build
$ make
$ ./build/sbin/unitd
Fixes: 5a37171f73 ("Added default values for pathnames.")

In BSD systems, it's usually </var/db> or some other dir under </var>
that is not </var/lib>, so $statedir is a more generic name. See
hier(7).

While here, default debhelper compat level bumped to 11 (this is the
version installed out of the box on Ubuntu 18.04 "bionic" which is
the oldest one from supported distros).
To support Go modules, the unit-go module should be platform independent.
All platform-dependent logic is moved to libunit, so the unit-dev package
should be installed before building unit-go.
