d04623678c70ff58a20fb5c35d33cb8f483f1efb depends: always set CMAKE_INSTALL_LIBDIR=lib/ (fanquake)
Pull request description:
Set `CMAKE_INSTALL_LIBDIR=lib/` and `CMAKE_POSITION_INDEPENDENT_CODE=ON` globally in depends, rather than per-package. `CMAKE_INSTALL_LIBDIR=lib/` is needed to override the annoying [`GNUInstallDirs`](https://cmake.org/cmake/help/latest/module/GNUInstallDirs.html) `lib` vs `lib64` behaviour, and we always want PIC code. The PIC commit is the counterpart to the same Autotools change in #29488. I'm PRing these commits as I have a CMake branch building on top, and want to avoid adding the same workarounds to every package we are going to touch, but these can go in separately as the build should be tested for existing packages (i.e multiprocess).

utACK 76045bb9d6808931cd0f2933203b5b611e032ec8. Both changes make sense to me, and both can be overridden if needed, though I can't imagine we'd need to.

Pull request description:
Change to always install libmultiprocess into `lib/`. On some systems (my Fedora aarch64 box), libmultiprocess was being installed into `lib64/`, and then configure would fail to pick it up, because we only add `lib/` to pkgconfig/ldflags out of depends. Rather than adding lib64 to those, I opted for installing libmultiprocess into lib, with every other dependency we build.
This was broken in our build after https://github.com/chaincodelabs/libmultiprocess/pull/79 upstream.

63c0c4ff10b2f6ed8510ef372a5b1f6a6494b179 depends: reuse _config_opts for CMake options (Cory Fields)
Pull request description:
Context: I'm [currently experimenting with building our depends with CMake when possible](https://github.com/theuni/bitcoin/commits/depends-cmake) as part of our future transition to CMake. Specifically zmq, libevent, libnatpmp, and miniupnpc all have existing CMake buildsystems. Building them with CMake will allow us to drop several deps that we currently have (autoconf, automake, pkg-config, etc) which would be unfortunate to carry over after the switch-over.
But that's not relevant for this PR. This is just a very simple change that makes the above work easier to experiment with as it [adds a needed feature for CMake packages](5733dc2000 (diff-e6ed342a25092e0a6d0308e0bfd826044578847132cc6726ac4afa2ca767b61aR20)). It's a no-op for the current builds.

From commit description:
This will allow us to use the existing machinery for filtering by arch, os, debug/release, etc.
For example, the following becomes possible for libevent when building with CMake:
`$(package)_config_opts_release=-DEVENT__DISABLE_DEBUG_MODE`
Now the define is only set when not building depends with DEBUG=1

c0f5cc14ef9fae2b2de4222ee061729629ebb6b4 build: Fix `libmultiprocess` cross-compiling to Linux hosts (Hennadii Stepanov)
Pull request description:
To successfully call the [`capnp_generate_cpp()`](d576d975de/CMakeLists.txt (L45)) function, the `libmultiprocess` build system must be provided with paths to the native `capnp` and `capnpc-c++` tools.
This [comment](https://github.com/bitcoin/bitcoin/issues/24387#issuecomment-1054776195) points the same:
> I think `packages/libmultiprocess.mk` probably needs to be passing a `-DCAPNP_EXECUTABLE=.../depends/arm-linux-gnueabihf/native/bin/capnp` argument to cmake. Also the package should have dependencies on both `capnp` and `native_capnp`.

7c218dacd0e9602b8f755be42e96c49706f96305 build: specify cmake build dir for multiprocess depends build (fanquake)
Pull request description:
When no build dir is specified, cmake will warn:
```bash
Preprocessing libmultiprocess...
Configuring libmultiprocess...
CMake Warning:
No source or binary directory provided. Both will be assumed to be the
same as the current working directory, but note that this warning will
become a fatal error in future CMake releases.
```
It's unclear if this will actually ever become an error, but it's also easy
enough to just supply the directory, and save this maybe breaking in
future.

Code review ACK 7c218dacd0e9602b8f755be42e96c49706f96305. I guess the purpose of the warning is to encourage people not to build in the source directory, but reasons for encouraging this don't really apply to the depends build system, so it is appropriate to disable the warning.

Pull request description:
This PR is part of the [process separation project](https://github.com/bitcoin/bitcoin/projects/10).
---
This PR consists of build changes only. It adds an `--enable-multiprocess` autoconf option (off by default and marked experimental), that builds new `bitcoin-node` and `bitcoin-gui` binaries. These currently function the same as existing `bitcoind` and `bitcoin-qt` binaries, but are extended in #10102 with IPC features to execute node, wallet, and gui functions in separate processes.
In addition to adding the `--enable-multiprocess` config flag, it also adds a depends package and autoconf rules to build with the [libmultiprocess](https://github.com/chaincodelabs/libmultiprocess) library, and it adds new travis configuration to exercise the build code and run functional tests with the new binaries.
The changes in this PR were originally part of #10102 but were moved into #16367 to be able to develop and review the multiprocess build changes independently of the code changes. #16367 was briefly merged and then reverted in #18588. Only change since #16367 has been dropping the `native_boost.mk` depends package which was pointed out to be no longer necessary in https://github.com/bitcoin/bitcoin/pull/16367#issuecomment-596484337 and https://github.com/bitcoin/bitcoin/pull/18588#pullrequestreview-391765649
