[libclang] Forward isInline for NamespaceDecl to libclang

[nik]

Did you forget to push the change to c-index-test.c?

Otherwise fine with me.

[yvvan]

Seems so.

[nik]

Adapted c-index-test.c and added function to libclang.exports.

[nik]

...and increased CINDEX_VERSION_MINOR.

[nik]

LGTM

  * The version constants for the libclang API.
  * CINDEX_VERSION_MINOR should increase when there are API additions.
  * CINDEX_VERSION_MAJOR is intended for "major" source/ABI breaking changes.
  *
  * The policy about the libclang API was always to keep it source and ABI
  * compatible, thus CINDEX_VERSION_MAJOR is expected to remain stable.
