Future releases of GCC are planning to remove[0] default support for
some old features that were removed from C99 but GCC still accepts.
We can test for these changes by using the following -Werror=
directives
-Werror=implicit-int
-Werror=implicit-function-declaration
-Werror=int-conversion
-Werror=strict-prototypes
-Werror=old-style-definition
Doing so revealed an issue with the auto/ tests in that the test
programs always define main as
int main()
rather than
int main(void)
which results in a bunch of errors like
build/autotest.c:3:23: error: function declaration isn't a prototype [-Werror=strict-prototypes]
3 | int main() {
| ^~~~
build/autotest.c: In function 'main':
build/autotest.c:3:23: error: old-style function definition [-Werror=old-style-definition]
The fix was easy, it only required fixing the main prototype with
find -type f -exec sed -i 's/int main() {/int main(void) {/g' {} \;
Regardless of these upcoming GCC changes, this is probably a good thing
to do anyway for correctness.

Currently almost all Unit object files depends on generated nxt_version.h.
This patch adds missing dependence and fixes running make with multiple
jobs.
This closes #318 issue on GitHub.

Some Perl compile options affects ABI and not using them while compiling
our module resulted in non-working build.
Notably on 32-bit Debian 10, Perl is built with -D_FILE_OFFSET_BITS=64
and our module after being compiled without this option caused segmentation
faults in unexpected places.

It's surplus option because the perl executable returns the proper path.
Also the Perl module configure script was cleaned up a bit.
Note that NXT_PERL_LDOPTS already contains the library path.

_GNU_SOURCE is required there to expose off64_t and other types.

Library now used in all language modules.
Old 'nxt_app_*' code removed.
See src/test/nxt_unit_app_test.c for usage sample.
