Due to the overloading behavior in sub-classes, access to the methods
returning const types in Item were not accessible from the Item
subclasses. This change adds the using statements necessary to fix that.

This CL adds two new ViewTstr and ViewBstr Item types that hold
strings as string_view and basic_string_view<uint8_t> types
instead of std::string or std::vector<uint8_t>, respectively.
This allows for zero-copy parsing of CBOR (mainly strings),
which is useful in low-memory environments like the apploader
where CBOR data can contain large bstr values.

Semantic tagging in libcppbor was a bit cumbersome to use, with tags
treated as separate items, requiring code that analyzes tagged data to
pay attention to the tags. Among other issues, that violates the
intention of semantic tagging in CBOR, which, per the RFC, does not
require decoders to understand tags. This CL changes that behavior so
that code that walks a parsed Item tree will not "see" the tags unless
it looks for them, by calling "Item::semanticTagCount()" and then
"Item::semanticTag()". Nested tags are supported.

This safe downcast template was never used and is hard to implement
with the coming SemanticTag changes, so this CL removes it.

This CL changes Map storage to use a vector of pairs, which removes
the need to copy the contents twice to sort them and makes it easy to
support Map iteration. Support for recursive canonicalization is
added as well, and Map::get() uses a binary search when the map is
canonicalized.

Other changes coming require non-const methods for safe downcasting,
but this change stands alone since not having them was clearly an
oversight.

Refactor to remove CompoundItem. It was a way to share some common
code between Array and Map, and later Semantic, but the
representations of those classes need to diverge so it adds no value.

1. Add pretty-printing (moved from IdentityCredentialSupport)
2. Add EncodedItem to make it easy to add already-encoded CBOR.
3. Add Map canonicalization.
4. Add support for adding enums as integers.

This commit alters the binary names in the Android.bp file to avoid
conflicts with the internal copy of libcppbor in hardware/interfaces.
Once checked in, the copy will be removed and the binary names will be
reverted back to normal. This is to avoid chicken and egg build errors.
Test: tests are under tests/

This reverts commit a7b145a6a5d05b89e9769ffea84d1068ef32bd4e.
Reason for revert: Need to submit with altered binary names

This commit just populates the repository with the code from the google
github repository
Test: tests/cppbor_test.cpp contains the relevant tests
