This is the "official" constant for arm64. We also have another constant
for arm64 (called BP_ARM64), which was used by breakpad while there was
no official constant for arm64 available.
The architecture enum contains two kinds of contstants: the "official" ones
defined by Microsoft, and unofficial constants added by breakpad to cover the
architectures not described by the first ones.
Up until now, there was no big need to differentiate between the two. However,
now that Microsoft has defined
https://docs.microsoft.com/en-us/windows/win32/api/sysinfoapi/ns-sysinfoapi-system_info
a constant for ARM64, we have a name clash.
This patch renames all breakpad-defined constants with to include the prefix
"BP_". This frees up the name "ARM64", which I'll re-introduce with the new
"official" value in a follow-up patch.

This is a continuation of the YAML library error reporting
refactoring/improvement and the idea by itself was mentioned
in the following thread:
https://reviews.llvm.org/D67182?id=218714#inline-603404
This performs a cleanup of all object emitters in the library.
It allows using the custom one provided by the caller.
One of the nice things is that each tool can now print its tool name,
e.g: "yaml2obj: error: <text>"
Also, the code became a bit simpler.

Summary:
The code for serializing minidumps was living in MinidumpYAML.cpp
so that it would be accessible from unit tests. While this had its
advantages, it was also unfortunate because it broke symmetry with all
other yaml2obj serializers.
Fortunately, nowadays all of yaml2obj is a library, so we don't need to
do anything special. This patch improves the code consistency by moving
the serialization code to MinidumpEmitter.cpp to match the style used in
other backends. It also removes the writeAsBinary entry point in favor
of the more general convertYAML interface.
This patch is just massaging the code a bit. There shouldn't be any
functional change here.

Summary:
Strings in minidump files are stored as a 32-bit length field, giving
the length of the string in *bytes*, which is followed by the
appropriate number of UTF16 code units. The string is also supposed to
be null-terminated, and the null-terminator is not a part of the length
field. This patch:
- adds support for reading these strings out of the minidump file (this
implementation does not depend on proper null-termination)
- adds support for writing them to a minidump file
- using the previous two pieces implements proper (de)serialization of
the CSDVersion field of the SystemInfo stream. Previously, this was
only read/written as hex, and no attempt was made to access the
referenced string -- now this string is read and written correctly.
The changes are tested via yaml2obj|obj2yaml round-trip as well as a
unit test which checks the corner cases of the string deserialization
logic.

Summary:
This patch adds the ability to read a yaml form of a minidump file and
write it out as binary. Apart from the minidump header and the stream
directory, only three basic stream kinds are supported:
- Text: This kind is used for streams which contain textual data. This
is typically the contents of a /proc file on linux (e.g.
/proc/PID/maps). In this case, we just put the raw stream contents
into the yaml.
- SystemInfo: This stream contains various bits of information about the
host system in binary form. We expose the data in a structured form.
- Raw: This kind is used as a fallback when we don't have any special
knowledge about the stream. In this case, we just print the stream
contents in hex.
For this code to be really useful, more stream kinds will need to be
added (particularly for things like lists of memory regions and loaded
modules). However, these can be added incrementally.

to reflect the new license.
We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.
Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.
