[edk2-devel] [PATCH v2] BaseTools:Extend the binary cache to support library cache

[Steven Shi]

V2 change:
Simplify the library cache implementation and remove
CacheRestored flag based filter. Use the current
CanSkipbyHash() filter in AddDependency() instead.

V1 change:

https://bugzilla.tianocore.org/show_bug.cgi?id=1797

Current binary cache doesn't support to save and restore
the library module. If a driver module cache miss happen,
all its dependency library modules need rebuild which
is very time-consuming. This patch is to entend the binary
cache to support library.
