cd42e38013 FlannBasedMatcher(LshIndex) in the feature2d optimization for continuance additional train() 
Current implementation of miniflann is releasing the trained index, and
rebuilding the index from the beginning.
But, some indexing algorithms like the LSH are able to add the indexing
data after that.
This branch is implementation of that optimization for LshIndex
FlannBasedMatcher in the feature2d.

fec697b390 Silenced a few -Wcast-align warnings in the headers. 
We don't use -Wcast-align ourselves, but the headers trigger warnings
for those users who do, which is not nice.

a9975b144a Fixed a bug in FLANN resulting in uninitialized accesses. 
This is fixed upstream in mariusmuja/flann@b615f26, but that fix
would break binary compatibility, so I had to make a different one.

Since the bug isn't quite obvious, here's an explanation. In the const
version of any::cast, if policy is a small_any_policy, its get_value
returns its input argument. So r becomes a pointer to obj, and the
return value is a reference to a local variable, which is invalidated
when the function exits.

d9f71b762f Deleted almost all of the precomp.cpp files. 
Looks like we don't actually use them; when creating precompiled headers
with Visual C++, a dummy .cpp is created at build time.
