Problem: When using packages an "after" directory cannot be used.
Solution: Add the "after" directory of the package to 'runtimepath' if it
exists.

Problem: For plugins in packages, plugin authors need to take care of all
dependencies.
Solution: When loading "start" packages and for :packloadall, first add all
directories to 'runtimepath' before sourcing plugins.

It appears that used msgpack library is not able to parse back message created
by msgpack_rpc_from_object() if nesting level is too high, so log_server_msg now
cares about msgpack_unpack_next() return value. Also error message from
server_notifications_spec.lua is not readable if something is wrong (though at
least now it does not crash when parsing deeply nested structures).
log_server_msg() in the test reports
[msgpack-rpc] nvim -> client(1) [error] "parse error"
This removes some stack overflows in new test regarding deeply nested variables.
Now in place of crashing vim_to_object/msgpack_rpc_from_object/etc it crashes
clear_tv with stack overflow.
This ought to prevent stack overflow, but I do not see this actually working:
*lua* code crashes with stack overflow when trying to deserialize msgpack from
Neovim, Neovim is fine even if nesting level is increased 100x (though test
becomes very slow); not sure how recursive function may survive this. So it
looks like there are currently only two positive effects:
1. NULL lists are returned as empty (#4596).
2. Functional tests are slightly more fast. Very slightly. Checked for Release
build for test/functional/eval tests because benchmarking of debug mode is
not very useful.
Actual value on FreeBSD is -31, UV_EMLINK was obtained from
/usr/include/asm-generic/errno-base.h (there EMLINK is defined as 31 there).
This may actually be something else, but I do not think so as “Too many links”
description also fits in. [Man page][1] agrees with me, search for `[EMLINK]`
([linux man page][2] also specifies ELOOP explicitly in a similar section).
