It is a common idiom to look for a function or a specific type or
a header in various locations/libraries, and it can be confusing to
see the (seemingly) identical compiler check being done multiple
times.
Now we print the dependencies being used when a compiler check is run
Before:
Checking for function "fbGetDisplay": NO
Checking for type "GLeglImageOES": YES
Checking for function "asinh": YES
After:
Checking for function "fbGetDisplay" with dependency egl: NO
Checking for type "GLeglImageOES" with dependencies glesv2, gl: YES
Checking for function "asinh" with dependency -lm: YES
This makes any warning message printed by meson raise an exception,
intended to be used by CI and developpers to easily catch deprecation
warnings and other potential issues.
Instead of just printing the message in the exception, if it's
a MesonException, also print the file and the line number. If it's an
unknown exception, print the entire traceback so that we can pin-point
what the Meson bug causing it is.
This change still relies on the older 'ANSICON' environment check as a
fallback, in the event we're on "not Windows 10". (Calling
`SetConsoleMode` with unsupported values results in a 0 being returned)
As written in PR #2856, this code isn't quite right.
An ArgumentNode object can evaluate as False (if it's arguments attribute is
an empty sequence).
If that happens, we then try to hand the location kwarg down to print(),
rather than removing it, which causes an invalid keyword argument exception.
This failure can be seen e.g. when generating for gnome-twitch (See [1])

Examples:
meson.build:2:0: ERROR: Dependency is both required and not-found
meson.build:4: WARNING: Keyword argument "link_with" defined multiple times.
These are already matched by the default compilation-error-regexp-alist in
emacs.
Also:
Don't start 'red' markup until after the \n before an error
Unabsorb full-stop at end of warning with location from mlog.warning()
Update warning_location test
configure a detection method, for those types of dependencies that have
more than one means of detection.
The default detection methods are unchanged if 'method' is not
specified, and all dependencies support the method 'auto', which is the
same as not specifying a method.
The dependencies which do support multiple detection methods
additionally support other values, depending on the dependency.
