[Omake] SVN Commit: OMake Build System [0.9.8.x] (Rev. 10579)

[Jason Hickey]

Add .STATIC rules.  This is different from a "static. =" section.

   - .STATIC rules are delayed; they are evaluated only if the value is needed.
   - .STATIC rules allow dependencies, and explicit variables.
   - The values are stored in .omakedb

* Basic usage:

    .STATIC:
        println(foo)
        X = 1
    Y = $X

The variable X is exported.  The rule is evaluated if the value for $X is needed,
but it is lazy.  The definition of Y does not force evaluation.

* With dependencies:

   .STATIC: x.input
       X = $(expensive-function x.input)

This is be evaluated if x.input changes and X is forced.

* Exporting variables

   .STATIC: X: x.input
       Y = 1
       X = $Y

Y is not exported from the section.
