Emit a detailed deprecation warning that explains what to do instead.
Also add a unittest.
```
DEPRECATION: target prog links against shared module mymod, which is incorrect.
This will be an error in the future, so please use shared_library() for mymod instead.
If shared_module() was used for mymod because it has references to undefined symbols,
use shared_libary() with `override_options: ['b_lundef=false']` instead.
```
Fixes https://github.com/mesonbuild/meson/issues/9492
So that editors that can fold code (vim, vscode, etc) can correctly fold
functions, instead of getting confused by code that doesn't follow the
current indention. Also, it makes the code easier to read.
D lang compilers have an option -release (or similar) which turns off
asserts, contracts, and other runtime type checking. This patch wires
that up to the b_ndebug flag.
Fixes#7082
Initially produced using:
for d in "test cases/failing/"* ; do rm -r _build ; ./meson.py setup "$d" _build | grep ERROR >"$d"/expected_stdout.txt; done
then converted to json with jq using:
jq --raw-input --slurp 'split("\n") | {stdout: map({line: select(. != "")})}' expected_stdout.txt >test.json
or merged with existing json using:
jq --slurp '.[0] + .[1]' test.json expected.json >test.json.new
v2:
Add some comments to explain the match when it isn't totally obvious
v3:
Add or adjust existing re: in expected output to handle '/' or '\' path
separators appearing in message, not location.
v4:
Put expected stdout in test.json, rather than a separate expected_stdout.txt file
Park comments in an unused 'comments' key, as JSON doesn't have a syntax for comments
