This allows us to automatically get the target type-specific behavior
with regards to the out_only semantics (added in the previous commit)
instead of passing it explicitly from each call site.
|
|
Also:
- Move the $target.*() function family from functions-name.cxx to separate
functions-target.cxx.
- Get rid of the separate $process_path_ex.*() family, merging it with
$process_path.*().

This is relied upon by the parser to provide conversion/concatenation
semantics consistent with untyped values. Note that we handle NULL values
only for types that have empty representation.

The $find() function returns true if the sequence contains the specified
value. The $find_index() function returns the index of the first element
in the sequence that is equal to the specified value or $size(<sequence>)
if none is found. For string sequences, it's possible to request case-
insensitive comparison with a flag.

$is_a() returns true if the <name>'s target type is-a <target-type>. Note
that this is a dynamic type check that takes into account target type
inheritance.
$filter[_out]() return names with target types which are-a (filter) or
not are-a (filter_out) one of <target-types>.
In particular, these functions are useful for filtering prerequisite
targets ($<) in ad hoc recipes and rules.

Available overloads:
$sort(<names> [, <flags>])
$sort(<ints> [, <flags>])
$sort(<strings> [, <flags>])
$sort(<paths> [, <flags>])
$sort(<dir_paths> [, <flags>])
The following flag is supported by the all overloads:
dedup - in addition to sorting also remove duplicates
Additionally, the strings overload also support the following flag:
icase - sort ignoring case
Note that on case-insensitive filesystem the paths and dir_paths overload's
order is case-insensitive.

These functions can be used to query library metadata for options and
libraries that should be used when compiling/linking dependent targets,
similar to how cc::{compile,link}_rule do it. With this support it should
be possible to more or less re-create their semantics in ad hoc recipes.

All non-const global state is now in class context and we can now have
multiple independent builds going on at the same time.
