We can't yet enable the build by default since it pulls in networking functions
into libgkrust which runs afoul of the checks added in bug 1376621.

Configure the lmdb-rkv-sys Rust crate to use a smaller MDB_IDL_LOGN size in order to reduce allocations when opening an LMDB environment in read-write mode.
@glandium I adopted the configuration strategy you suggested of creating a "feature" for each reasonable value for the MDB_IDL_LOGN macro. Fortunately, the range of reasonable values is fairly small.
@nanj Based on your evalution in https://github.com/mozilla/lmdb/pull/2, a value of "9" for this macro should aggressively reduce the allocations while still supporting our existing use cases. But I'm open to increasing it, if you think a higher initial value would be preferable.

Before bug 938437, we had a rather large and error-prone
nsStaticXULComponents.cpp used to register all modules. That was
replaced with clever use of the linker, which allowed to avoid the mess
that maintaining that file was.
Fast forward to now, where after bug 1524687 and other work that
preceded it, we have a much smaller number of remaining static xpcom
components, registered via this linker hack, and don't expect to add
any new ones. The list should eventually go down to zero.
Within that context, it seems to be the right time to get rid of the
magic, and with it the problems it causes on its own.
Some of those components could probably be trivially be converted to
static registration via .conf files, but I didn't want to deal with the
possible need to increase the number of dummy modules in XPCOMInit.cpp.
They can still be converted as a followup.

This patch contains three fixes.
1) As in Bug 1515982, we use the constant for RT_MANIFEST instead of
the define, which needs winuser.rh to be included
2) We stop exempting the mingw builds from RCINCLUDE in
toolkit/library/moz.build which causes us to miss all of the
resources in xul.dll
3) We explicitly include IA2Marshal.dll instead of relying on
compiler magic to include it for us.

This is needed for cross-language LTO (bug 1512723). We don't want to block on waiting for 1.34's release, so we'll get a head start now, but we'll update to the final 1.34 release when available. Rust Forge estimates the release at 11 April.

This commit introduces a Rust XPCOM component,
`mozISyncedBookmarksMerger`, that wraps the Dogear crate for
merging and applying synced bookmarks.
How this works: `SyncedBookmarksMirror.jsm` manages opening
the connection, initializing the schema, and writing incoming
items into the mirror database. The new `mozISyncedBookmarksMerger`
holds a handle to the same connection. When JS code calls
`mozISyncedBookmarksMerger::apply`, the merger builds local and
remote trees, produces a merged tree, applies the tree back to Places,
and stages outgoing items for upload in a temp table, all on the
storage thread. It then calls back in to JS, which inflates Sync
records for outgoing items, notifies Places observers, and cleans up.
Since Dogear has a more robust merging algorithm that attempts to fix
up invalid trees, `test_bookmark_corruption.js` intentionally fails.
This is fixed in the next commit, which changes the merger to handle
invalid structure.

This commit wraps just enough of the mozStorage API to support the
bookmarks mirror. It's not complete: for example, there's no way
to open, clone, or close a connection, because the mirror handles
that from JS. The wrapper also omits shutdown blocking and retrying on
`SQLITE_BUSY`.
This commit also changes the behavior of sync and async mozStorage
connections. Async (`mozIStorageAsyncConnection`) methods may be called
from any thread on any connection. Sync (`mozIStorageConnection`)
methods may be called from any thread on a sync connection, and from
background threads on an async connection. All connections now QI
to `mozIStorageConnection`, but attempting to call a sync method on
an async connection from the main thread throws.
Finally, this commit exposes an `OpenedConnection::unsafeRawConnection`
getter in Sqlite.jsm, for JS code to access the underlying connection.

This introduces features in the jsrust crate, so we can enable/disable
compilation for a specific platform at compile-time. It also does only select
the architecture targeted by the JIT, which should result in slightly lower
compilation times on every platform, and lower binary sizes too.

Consequently, this removes:
- MOZ_LIBPRIO, which is now always enabled.
- non_msvc_compiler, which is now always true.
- The cl.py wrapper, since it's not used anymore.
- CL_INCLUDES_PREFIX, which was only used for the cl.py wrapper.
- NONASCII, which was only there to ensure CL_INCLUDES_PREFIX still
worked in non-ASCII cases.
This however keeps a large part of detecting and configuring for MSVC,
because we still do need it for at least headers, libraries, and midl.

Rust ships with some natvis files that enable nicer display of Rust standard
library types in Microsoft's debuggers. rustc will add the right linker
options to include them when it invokes the linker but since we don't link
libxul with rustc we need to explicitly pass them to the linker ourselves.
This change locates all natvis files in the Rust sysroot and adds them
to the libxul link line.

Enough linux-based systems don't have libsecret that we can't make it a
requirement on linux. For those that do, however, we can dynamically load the
library at runtime. For those that don't, we can fall back to NSS.

Until rust 1.28, there was no stable way to change the allocator used by
rust code. In bug 1280578, we hooked HeadAlloc/HeapFree/HeapRealloc,
that the default rust system allocator uses. On other platforms, rust
code just ended up using malloc/free/realloc like everything else.
As of rust 1.28, though, it is now possible to use the GlobalAlloc trait
and the #[global_allocator] attribute to set an allocator. On Windows,
this can allow us to hook mozjemalloc directly, rather than using an
indirection through HeapAlloc/etc. (which require an extra call to
GetProcessHeap), so let's do this. On other platforms, this just ends up
doing the same thing as the default rust system allocator (except for
the memalign limit on 32-bits platforms).
We still need the HeapAlloc/etc. hooks for some C++ code using it, though.
Another benefit is that the HeapAlloc GlobalAlloc implementation needs
to do its own memalign, which it does by overallocating and aligning
manually. We obviously don't need to do this when we using
memalign/_aligned_malloc directly.
