* Build-plan: Extensively revised the build plan process so that
:DEFSYSTEM-DEPENDS-ON would work correctly, even when depended on systems
change (which didn't work before). See our ELS demonstration about it:
"Delivering Common Lisp Applications with ASDF 3.3"
< https://github.com/fare/asdf2017 >
* Internals: to support the above, many ASDF internals have changed.
ASDF now has the notion of multiple build phases to a common build session
(which generalizes the previous build cache). ASDF considers loading a .asd
file as an operation DEFINE-OP, and tracks as dependencies files mentioned
during in :LOAD-FILE-FORM statements, etc. Some code has moved to new
files or among old files, and between packages. Actions are now
uniformly represented as a CONS of an OPERATION and a COMPONENT, where
in some cases previously only the class of the operation was
preserved. Forcing is constrained to be uniform across all phases of a
top level ASDF operation invocation. Fixed the protocol for
resetting systems being (re)defined, allowing subclasses to define
default slot values. Remove *LOAD-SYSTEM-OPERATION*, as the current
maintainer of ECL, for which it was originally designed, decided
that it could never be made to work properly, after all.
* ASDF&UIOP: Tweak dependencies between ASDF and UIOP. To avoid DEFINE-OP
circularity, asdf.asd with no longer causes uiop.asd to be loaded.
A standalone UIOP won't be loaded at all unless it's strictly more recent
than ASDF.
* Tests: tests for new capabilities and bugs. Test backtraces can be disabled.
* Documentation: a number of improvements and clarifications.
* Feature: a new feature :asdf3.3
* ECL: restored the deprecated function MAKE-BUILD, removed in 3.2.0,
in a way that works on top of supported APIs (we still recommend you migrate
to these supported APIs). Also stop using the deprecated COMPUTE-INIT-NAME.
* Deprecation: starting to emit STYLE-WARNINGs for deprecated
functions. Will gradually escalate to true WARNINGs and then ERRORs.
