For example, implicitly converting a table to a string works in LuaJIT,
but needs to be done explicitly with tostring() in Lua 5.1.
This can cause issues when testing a non-JIT build if eq(), for example,
fails with a table argument. E.g: eq({}, {1}) will not print the details
of the assertion failure, but will instead print a less helpful "string
expected, got table" error.
The official developer documentation in in :h dev-lua-doc specifies to
use "--@" for special/magic tokens. However, this format is not
consistent with EmmyLua notation (used by some Lua language servers) nor
with the C version of the magic docstring tokens which use three comment
characters.
Further, the code base is currently split between usage of "--@",
"---@", and "--- @". In an effort to remain consistent, change all Lua
magic tokens to use "---@" and update the developer documentation
accordingly.
- The previous commit lost information in the tests. Instead, add some
more "normalization" substitutions in pcall_err(), so that the general
shape of the stacktrace is included in the asserted text.
- Eliminate contains(), it is redundant with matches()
- Add vim variable meta accessors: vim.env, vim.{g,v,w,bo,wo}
- Redo gen_char_blob to generate multiple blobs instead of just one
so that multiple Lua modules can be inlined.
- Reorder vim.lua inclusion so that it can use previously defined C
functions and utility functions like vim.shared and vim.inspect things.
- Inline shared.lua into nvim, but also keep it available in runtime.
- Rename `meth_pcall`.
- Make `pcall_err` raise an error if the function does not fail.
- Add `vim.pesc()` to treat a string as literal where a Lua pattern is
expected.
luassert uses 3 by default, which is often not enough.
Instead of documenting how to increase it, let's use a more fitting
(sane) default of 100 levels.
This is where "pure functions" can live, which can be shared by Nvim and
test logic which may not have a running Nvim instance available.
If in the future we use Nvim itself as the Lua engine for tests, then
these functions could be moved directly onto the `vim` Lua module.

Automatically include all "global helper" util functions in the
unit.helpers and functional.helpers and modules. So tests don't need to
expicitly do:
local global_helpers = require('test.helpers')
Note: the test fails on non-Windows CI (Travis linux, Quickbuild bsd):
even on master before the env.c changes in this patch-series.
Maybe the unix part of printenv-test.c needs to be revisited.

tmpdir_get() may be an absolute path, but we invoke glob() with
a relative `initial_path`.
That can lead to this error:

Vim's code calls `call_shell` directly from `get_system_output_as_rettv`
whereas in Nvim this function has been rewritten to not call `call_shell` but to call
`os_system` via `do_os_system`, losing the support for profiling and verbose.
Changing the code to call `call_shell` from `get_system_output_as_rettv`
seems to be too complicated to be worth it on the current version of the
code. So this commit duplicates the relevant code.
