Remove usages of deprecated APIs of corelib

- Replaced the usages of deprecated APIs of corelib by corresponding
  alternatives in the library code and documentation.

- Modified the tests to make them build when deprecated APIs disabled:
    * Made the the parts of the tests testing the deprecated APIs to
      be compiled conditionally, only when the corresponding methods are
      enabled.
    * If the test-case tests only the deprecated API, but not the
      corresponding replacement, added tests for the replacement.
