In the animation transform code, `T_AUTOMERGE` was used
to indicate that the duplicated keys need to be merged.
In perparation of #111051, this no longer makes much sense because
in grease pencil we cannot have two keys in the same channel at the same
frame.
This PR replaces the `T_AUTOMERGE` flag in the animation code to
`T_DUPLICATED_KEYS` to indicate that the transform is being called
with duplicated keyframes.

Using ClangBuildAnalyzer on the whole Blender build, it was pointing
out that BLI_math.h is the heaviest "header hub" (i.e. non tiny file
that is included a lot).
However, there's very little (actually zero) source files in Blender
that need "all the math" (base, colors, vectors, matrices,
quaternions, intersection, interpolation, statistics, solvers and
time). A common use case is source files needing just vectors, or
just vectors & matrices, or just colors etc. Actually, 181 files
were including the whole math thing without needing it at all.
This change removes BLI_math.h completely, and instead in all the
places that need it, includes BLI_math_vector.h or BLI_math_color.h
and so on.
Change from that:
- BLI_math_color.h was included 1399 times -> now 408 (took 114.0sec
to parse -> now 36.3sec)
- BLI_simd.h 1403 -> 418 (109.7sec -> 34.9sec).
Full rebuild of Blender (Apple M1, Xcode, RelWithDebInfo) is not
affected much (342sec -> 334sec). Most of benefit would be when
someone's changing BLI_simd.h or BLI_math_color.h or similar files,
that now there's 3x fewer files result in a recompile.
Pull Request #110944
The `TD_NOTCONNECTED` flag is not set in all cases.
In some cases, such as Meshes, the `FLT_MAX` value better determines
when the `TrasData` is not "connected".
Therefore, this commit removes the `TD_NOTCONNECTED` flag and adapts
the code to rely on the `FLT_MAX` value instead.
These TrasDatas shouldn't even be created in these cases.
Caused by 5ed14e9269.
That commit accidentally removed the `copy_v2_v2_int(t->mval, mval);`
line which was responsible for initializing the value of `mval`.
In the 3D View, after navigating, the initial cursor position was
updated based on the relative position of the cursor in 3D space.
Now the initial relative position is maintained but moved closer to or
further from the 2d center based on zoom.
In order to avoid navigation hotkey conflicts during transform
operations, this commit implements the "Transform Navigation with Alt"
option.
This option is enabled by default and makes navigation hotkeys require
the `Alt` key during a transforming in the 3D View.
