platform_info_t is used to pass platform-specific information from the
kernel into the vmm. On aarch64, this is used to map the serial
peripheral and pass the resulting virtual address.

This patch converts the hypervisor to use delegates, dramatically
reducing the complexity of the hypervisor, while also providing a
cleaner interface for extensions.

The latest versions of Windows do not like having aligned memory freed
using "free", resulting in a segfault. Alighed memory is no longer
needed so this can be removed.

This patch addresses several bugs with the build system:
- Lack of Windows support
- Clang Tidy was not working properly
- Making modifications to the source code would compile, but would not
re-link resulting in issues
- Removed excess file copying
- Make clean now works
- Removed unused or confusing folders in the build folder as part of the
build process. It is now much easier to traverse the build folder for
dependencies
- The targets didn't work with extensions. This has been fixed.
In addition, the following was also done under this patch
- Intrinsics was moved to the top level and out of the VMM
- Platform files are now in a folder called "platform" instead of
"arch"
- All subprojects have the same include/src/tests files structure
- All intel specific code is properly organized to match intended
namespacing
- Removed dead code
- A small part of the VMCS was converted to use the delegate pattern
- All dependencies are now downloaded at configure time instead of
compile time.
- The cache directory is now cached by Travis CI
- CMake output better matches old build system
- Added make rebuild and separate clean targets to remove various parts
of the build depending on needs.
- Added targets for Clean, Tidy, Rebuild and Format for each subproject
- Re-organized the cmake logic so that macros are not spread out
- New validation removes unneeded complexity
- Removed the need for the compiler wrapper, and in doing so, we now
provide a simpilar set of toolchain files
- Removed the need for Git repos. All external dependencies are
downloaded using a zip or tarball
- Libcxx and Libcxxabi are now in their own files. Much similar logic
- Unit test CMake files have been greatly simplified
- Each subproject is unaware of it's prefix and no long use VMM,
USERSPACE or TEST variables in their cmake files
- Fixed bugs with the flags
- Renamed the varbiables in the default.cmake config to be more
consistent and easier to follow in the rest of the code

This patch cleans up some issues with formatting, and adds support
for C++ delegates. This implementation doesn't need malloc/free
and is as fast as a regular vtable lookup. Before the release
of v1.2, a lot of the inheritance currently being used with be
converted to delegates to increase modularity.

This header tests for predefined macros on both supported compilers to
determine the architecture being compiled for. Once detected, it defines
two macros:
- BF_ARCH string containing architecture name
- BF_{archname} empty macro for #ifdef tests
Currently supported combinations are:
- x64 on MSVC (via _MSC_VER and _X64)
- x64 on GCC and clang (via __GNUC__, __clang__, and __x86_64__)
- aarch64 on GCC and clang (via __GNUC__, __clang__, and __aarch64__)
Additionally, this header allows the user or the build system to modify
the architecture externally: defining BF_ARCH with -D disables the
checks and allows you to force an architecture flag.
