Subject: Support multiple install dirs for built/custom targets

You can now pass a list of strings to the install_dir: kwarg to
build_target and custom_target.

Custom Targets:
===============
Allows you to specify the installation directory for each
corresponding output. For example:

    custom_target('different-install-dirs',
      output : ['first.file', 'second.file'],
      ...
      install : true,
      install_dir : ['somedir', 'otherdir])

This would install first.file to somedir and second.file to otherdir.

If only one install_dir is provided, all outputs are installed there
(same behaviour as before).

To only install some outputs, pass `false` for the outputs that you
don't want installed. For example:

    custom_target('only-install-second',
      output : ['first.file', 'second.file'],
      ...
      install : true,
      install_dir : [false, 'otherdir])

This would install second.file to otherdir and not install first.file.

Build Targets:
==============
With build_target() (which includes executable(), library(), etc),
usually there is only one primary output. However some types of
targets have multiple outputs.

For example, while generating Vala libraries, valac also generates
a header and a .vapi file both of which often need to be installed.
This allows you to specify installation directories for those too.

    # This will only install the library (same as before)
    shared_library('somevalalib', 'somesource.vala',
      ...
      install : true)

    # This will install the library, the header, and the vapi into the
    # respective directories
    shared_library('somevalalib', 'somesource.vala',
      ...
      install : true,
      install_dir : ['libdir', 'incdir', 'vapidir'])

    # This will install the library into the default libdir and
    # everything else into the specified directories
    shared_library('somevalalib', 'somesource.vala',
      ...
      install : true,
      install_dir : [true, 'incdir', 'vapidir'])

    # This will NOT install the library, and will install everything
    # else into the specified directories
    shared_library('somevalalib', 'somesource.vala',
      ...
      install : true,
      install_dir : [false, 'incdir', 'vapidir'])

true/false can also be used for secondary outputs in the same way.

Valac can also generate a GIR file for libraries when the `vala_gir:`
keyword argument is passed to library(). In that case, `install_dir:`
must be given a list with four elements, one for each output.

Includes tests for all these.
