servo: Merge #18495 - Measure PropertyDeclaration more thoroughly (from nnethercote:derive-PropertyDeclaration); r=jdm This patch replaces the handwritten MallocSizeOf implementation for PropertyDeclaration with a derived one, which gives much more thorough measurement. This requires (a) deriving MallocSizeOf for a *lot* of additional types (most of which already have `derive(HeapSizeOf)` in Servo builds), and (b) implementing MallocSizeOf for a few more types in the `malloc_size_of` crate. These changes would significantly improve the reporting coverage for gmail if it weren't for the fact that SpecifiedUrl isn't measured due to a lack of clarity about its fields; that can be fixed as a follow-up once bug 1397971 has landed. <!-- Please describe your changes on the following line: --> --- <!-- Thank you for contributing to Servo! Please replace each `[ ]` by `[X]` when the step is complete, and replace `__` with appropriate data: --> - [X] `./mach build -d` does not report any errors - [X] `./mach test-tidy` does not report any errors - [ ] These changes fix #__ (github issue number if applicable). <!-- Either: --> - [ ] There are tests for these changes OR - [X] These changes do not require tests because testing is on the Gecko side. <!-- Also, please make sure that "Allow edits from maintainers" checkbox is checked, so that we can help you if you get stuck somewhere along the way.--> <!-- Pull requests that do not address these steps are welcome, but they will require additional verification as part of the review process. --> Source-Repo: Source-Revision: 097cea240fe9b1d96fa4ef5ffa984f09e0bd04f3

Please be apprised of the following Legal Notices:

A) The U.S. District Court for the Eastern District of Virginia has
ruled that the Netscape Navigator code does not infringe Wang's U.S.
Patent No. 4,751,669 ("the '669 Patent") because: 1) HTML is not
Videotex as defined by the '669 patent; 2) web servers are not central
suppliers; and 3) Navigator does not "connect," as defined by the '669
Patent, to web servers on the Internet. Wang may appeal this decision to
the Federal Circuit. Wang contended that its Patent disclosing a
"Videotex" system, is infringed by the following functionality in the
Netscape Navigator code: 1) the animated logo and status line indicators
--See Claims 1,8 and 9; 2) the "File Save As" function --See Claims
23-27; 3) Bookmarks and Rename Bookmarks in the Properties window --See
Claims 20-22; 4) storing HTML, GIF, and JPEG files and adding filename
extensions --See Claim 38

B) Intermind owns pending U.S. patent applications on communications
systems which employ metadata ("channel objects") to define a control
structure for information transfer. The Netscape code does not infringe
as released; however, modifications which utilize channel objects as
described by Intermind should be considered carefully. The following is
a statement from Intermind: "Intermind's claims fundamentally involve
the use of a control structure to automate communications. ...The
essence of Intermind's top claim is that two devices sender and receiver
have persistent storage, communicate over a network, and exchange a
control structure including metadata which describes: 1) what
information is to be updated, 2) when to update this information, and 3)
how to transfer the updated information. In addition, at least the
receiving device must be able to process the metadata in order to
perform the update determination and transfer. Any digital
communications system which incorporates all of these elements will be
covered by Intermind's patents." See

C) Stac, Inc., and its licensing agent Hi/fn, own several patents which
disclose data compression methods implementing an LZS compression
algorithm, including U.S. Patent Nos. 4,701,745 and 5,016, 009 ("the
Stac Patents"). The Netscape Communicator code does not perform
compression. If you modify the Netscape source code to perform
compression, please take notice of the Stac Patents.

D) Netscape Communications Corporation ("Netscape") does not guarantee
that any source code or executable code available from the
domain is Year 2000 compliant.
