Previously, the sdk snapshot would include all the entries from the
stub-flags.csv and all-flags.csv modular files generated by a single
bootclasspath_fragment. That included implementation details, i.e.
class members that are not part of a stable API or the hidden API which
meant that the sdk snapshots were implementation dependent.
This change removes the implementation details from the modular flag
files, i.e. those entries that are only marked as "blocked". When
comparing the files against the corresponding subset of the monolithic
files it assumes that any entries missing from the modular flag files
are blocked.

Previously, the signature-patterns.csv file included a lot of
implementation details, e.g. the signatures of dex members or inner
classes that are not part of any API, including the hidden API.
This change will remove all member signatures and inner class names
from the file and replace them with just the outermost qualified class
name.
That will still leave some implementation details, e.g. the names of
implementation only classes and packages.

Previously, a simple map from dex signature to the flags was used to
store the monolithic hidden API flags. This change replaces that with a
trie that uses packages and class names extracted from the signature
to map from the signature to the flags.
The signature is broken down into pieces consisting of package names,
class names and the remaining member signature. They are used in turn
to navigate through nodes in the trie to a Leaf that contains the flags
associated with the signature.
The flags can be retrieved from the trie in a number of ways:
* Using the complete signature to retrieve the flags for a single
member.
* Using a class name to retrieve the flags for all the members in a
class and any nested classes.
* Using a package wildcard to retrieve the flags for all the members in
the classes in that package.
* Using a recursive package wildcard to retrieve the flags for all the
members in the classes in that package and nested packages.
This will allow a bootclasspath_fragment to select a subset of the
monolithic flags to compare against itself without specifying the
signatures of every member of that set.
Before creating the trie an attempt was made to compute the subset by
iterating over all the signatures in the monolithic flags and matching
against a regular expression created from the patterns but that was too
slow. It took minutes to run whereas using the simple map or the trie
only takes a few seconds.

Previously, the signatures used to select the subset of the monolithic
flags were simply the signatures read from the modular flags file. This
change moves the creation of the signature list into a separate script
that outputs the signatures to a file and then passes the path through
Soong from the bootclasspath_fragment modules that create it to the
platform_bootclasspath module that uses it to compare the modular
flags against the monolithic flags.
Currently, the signatures are the full signatures but follow up changes
will replace them with patterns (hence the name) that avoids having to
include implementation details in the hidden API flags that are output
as part of a bootclasspath_fragment's snapshot.
This change moves the stub flags related code next to the all flags
related code as they are treated in a similar way.

Previously, the compare_signature_flags compared the full set of
monolithic flags against the modular flags and just ignored any
monolithic flags for a signature that was not present in the modular
flags. It essentially performed two tasks, identifying the subset of
the monolithic flags against which the modular flags should be compared
and then doing the actual comparison.
This change separates those two tasks, by first creating a dict that is
the subset of the monolithic flags against which the modular flags will
be compared and then do the comparison.
At the moment the subset is simply the set of monolithic flags
associated with the signatures that are present in the modular flags.
Follow up changes will provide other ways to select the subset.

Refactor verify_overlaps to make it testable and add tests for the
comparison. It does make one significant change in behavior which is to
read each of the files produced by a bootclasspath_fragment into a dict
before comparison, rather than reading and comparing them a row at a
time. That allows it to reuse the code to read a CSV into a dict.

Normally Soong does that automatically when it handles module names
specified in Android.bp properties. However not all <uses-library>
entries in the manifest correspond to real modules: some of the
optional libraries may be missing at build time. Therefor this script
accepts raw module names as spelled in Android.bp/Amdroid.mk and trims

Previously, if the --header property was not specified then merge_csv
would use a header constructed by sorting all the fields in the input
files. That required that any use of merge_csv which did not already
have headers in the required order would have to explicitly specify the
headers. That made it harder to use merge_csv as a generic tool as each
invocation needed to be aware of what headers were exported in the
output.
This change causes merge_csv to simply use the headers in the order in
which they are encountered in the input files. That removes the need to
specify the --header option when generating the index files.

compresses frame unwind information more efficiently,
and improves random-accessibility for lazy decompression.
Overall, the changes balance and the output size is same,
