filespecs: Implement new file: specifier behavior

PR-URL: https://github.com/npm/npm/pull/15900
Credit: @iarna

actions: Allow actions to return promises

extract: Eliminate extra callback

finalize: Rewrite finalize as promises

update-linked: Remove update-linked action

install: Remove obsolete invalid action filtering

fetch-package-metadata: Error on installing windows paths on non-windows systems

fetch-package-metadata: Read in modules installed inside of new links

finalize: Act on realpaths because we may be installing inside a link prior to the symlink being made

finalize: Create symlinks of directory deps

deps: Resolve ambiguity for file specifiers in the traditional way

deps: Set link and realpath properties for directory deps

inflate-bundled: Distinguish published bundles from lined modules

node: Add new fromLink attribute to track sourced-to-symlinks deps

diff-trees: Don't try to install deps that are already inside a link

fetch-package-metadata: Improve error messages for link failures

install: Run preinstall lifecycle after finalize

finalize: Start reading package.json files here

decompose-actions: Don't fetch or extract links

deps: Determine if a link matches spec based on where it points

deps: Compute correct save specifier for file spec

deps: Set the isInLink property on new children

deps: When finding the install location, don't walk up out of a symlink unless PRESERVE_SYMLINKS is on

diff-trees: Stop setting isInLink, this is now a first class property

diff-trees: Only exclude children of links from adding if they were already there behind the symlink

inflate-bundled: We are using isInLink now not fromLink

inflate-bundled: realpaths should be built on realpaths

node: Eliminate fromLink as a thing

node: Fill in values for inLink, isInLink & fromBundle

save: When updating a lock/shrinkwrap don't read the damn tree again

shrinkwrap: Fill in version per the new shrinkwrap spec

install: Make _inBundle purely a debugging artifact

inflate-shrinkwrap: Fix how bundle deps are inflated

save: Detect dependency type when saving

recalculateMetadata: Rewrite as simpler and synchronous

prune: Work off computed metadata

refreshPackageJson: Copy all of the in memory version over the on-disk version except empty items

install: Reduce normalize tree function to minimum

realize-package-specifier: Bring into closer alignment with spec

read-shrinkwrap: Use child.isTop not !child.parent

copy-tree: Don't crash of requires or requiredBy are missing

copy-tree: Initialize copied nodes

dedupe: use getRequested instead of child.package._requested

install: recompute the pkg relationships after finalize

Neccessary to align behavior with shrinkwraps where relationship information
isn't available until we read the module off disk.

install: Prune the tree after building it

install: Only save deps if we made changes

inflate-shrinkwrap: Better metadata while inflating
