This CL introduces the following strongly typed enums, which are meant
to replace raw integers in Chrome's layer on top of SQLite.
* SqliteResultCode represents all result codes.
* SqliteErrorCode represent a result code that's known to be an error.
This CL integrates each new type in one place, to give an idea of what
our code will look like once we adopt these new types.
* SqliteResultCode is integrated in
Database::ExecuteAndReturnResultCode().
* SqliteErrorCode is integrated in Database::OnSqliteError().
The new enums are declared in //sql/sqlite_result_code.h, together with
helper functions for converting raw integers returned by the SQLite API.
The values for the new enums are defined in a separate header,
//sql/sqlite_result_code_values.h. This is intended to help readability,
as sqlite_result_code.h has everything developers need to start using
the types, while the boilerplate is relegated to
sqlite_result_code_values.h.
Last, this CL moves the SqliteLoggedResultCode logic from
error_metrics.{h,cc} into the newly introduced files. This is done in
part because this type is also a strongly typed replacement for SQLite's
result codes, and in part because we want all the SQLite result code
conversion logic to share one mapping table.
