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 adds support for unordered_map. Specifically it adds support
for libm which is needed by unordered_map as it abuses the ceil
function for integer rounding in it's hash function.

This relocates and renames the memory manager to match the new source
tree structure. The code itself still needs a major overhaul, but the
public APIs should not change much after this patch.

- Add an isr_type in the idt class to avoid compiler cast errors
- Use relative paths with memory_manager/object_allocator.h and user_data.h
- Add trailing slash on the source install path in bfvmm/src/CMakeLists.txt.
Without the slash, the headers were being installed as
<prefix>/include/bfvmm/include/...
This patch adds the bfvmm namesapce to the check logic in the bfvmm.
This is the first of many PRs to add the bfvmm namespace and reduce the
need for hardcoding namespace logic into filenames / variable names

The bfvmm was not installing its headers, but instead was directly
searching for the includes from the source tree, resulting in name
collisions with extensions.
In addition, warnings were never working, and are by default turned off.
Travis however should ensure no warnings occur, which was not working
properly.

As part of the PTI patches, Linux now uses PCIDs to reduce the
cost of context switches. The current PCID is given by CR3[11:0],
and if this is not zero when CR4.PCIDE is set on a write to CR4,
a #GP is raised.
The promotion bug described in #573 was due to Bareflank
restoring the guest CR3 (in which CR3[11:0] was nonzero), and
then restoring the guest CR4, which was setting CR4.PCIDE. The
resulting #GP was raised with nothing to handle it, leading to a
triple fault.
Now Bareflank writes a copy of the guest CR3 with bits 11-0
clear, then writes the guest's CR4. Once the CR4 is
written, the guest's original CR3 is restored.
This patch re-enables codecov so that it can calculate our
current code coverage. This will likely result in failed tests
until code coverage is fixed.

This patch fixes two specific issues with extensions:
- The init_project macro was including <path>/../include which it
shouldn't be because we don't know how an extension will be setup, and
this could accidentially include unintended files.
- The add_vmm_exectuable provided to way to link shared and static
libraries at the same time, and as a result, was cumbersome to use.

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
