Add a new ashmem_init function that only dlopens libashmemd_client.
This allows the library to be preloaded in the zygote.
Test: boots, works

std::hash returns a 64 bit value, which is truncated to a 32 bit value
in ComputeHash. ubsan's implicit-unsigned-integer-truncation doesn't
like this implicit truncation and crashes the program. Explicitly strip
off the top order bits after computing the hash.
Remove the windows specific version of the hash computation. The windows
compile now uses clang, so this code is obsolete. This also avoids us
having to add __attribute__((no_sanitize("integer"))) to the windows
code.
This is needed to support Android booting with ubsan's
implicit-unsigned-integer-truncation option enabled.
Test: compiles and boots

- If file is unlinked, the mmapped region is still there.
- If file is truncated, a SIGBUS will be seen, and holding
the fd doesn't help.
Test: boots (sanity)

- Rename SparseBuilder to ImageBuilder, WriteSplitSparseFiles
to WriteSplitImageFiles, WriteToSparseFile to WriteToImageFile, etc.
- Add sparsify argument to ImageBuilder, WriteToImageFile, and
WriteSplitImageFiles
This allows lpmake to write non-sparse super image directly. Virtual
devices needs non-sparse images to work on.
Test: lpmake without --sparse

The purpose of having fine grain read/write control over the property
space is to help ensure the confidentiality of data stored in
properties. Leaking property values into the dmesg buffer on errors
exposes the value outside of the access control rules specified by
policy.
(arguably this is also true for the property name, not just the value.
However, property names are exposed in other places now, so the
incentive to fix this is lower. It would also take away a valuable
debugging tool.)

This is required for read() to function correctly
in Windows since it behaves differently in text mode and
binary mode and may cause unpredictable behavior depending
on the contents of the image file.
