This is implemented in the first commit (more details in commit description). The fix avoiding `bitcoin-wallet` dependency on libevent requires minor code changes, because `bitcoin-wallet` (unlike `bitcoin-tx`) links against code that calls `urlDecode` / `evhttp_uridecode`. This fix is implemented in the second commit (again details in the commit description). ACKs for top commit: jonasschnelli: utACK 01a3392b1b778fa4fcf568013326d6ea1de4fb3b.

2020-04-05Multiprocess build changesRussell Yanofsky
autotools and automake changes to support multiprocess execution. This adds a new --enable-multiprocess flag, and build configuration code to detect libraries needed for multiprocess support. The --enable-multiprocess flag builds new bitcoin-node and bitcoin-gui executables, which are updated in https://github.com/bitcoin/bitcoin/pull/10102 to communicate across processes. But for now they are functionally equivalent to existing bitcoind and bitcoin-qt executables.

2020-03-19build: fix sysctl() detection on macOSfanquake
sysctl() on *BSD takes a "const int *name", whereas sysctl() on macOS it takes an "int *name". So our configure check and sysctl() detection on macOS currently fails: ```bash /usr/include/sys/sysctl.h:759:9: note: candidate function not viable: no known conversion from 'const int [2]' to 'int *' for 1st argument int sysctl(int *, u_int, void *, size_t *, void *, size_t); ``` This change removes the name argument from the sysctl() detection check, meaning we will detect correctly on macOS and *BSD. For consistency we also switch to using the more generic, non-const version of the name parameter in the rest of our usage.

2020-01-26build: remove --large-address-aware linker flagfanquake
This flag was used when building 32-bit Windows executables, which we no-longer do, and is not accepted by the linker for any of the hosts we currently build for. i.e: ```bash checking whether the linker accepts -Wl,--large-address-aware... no ``` --large-address-aware If given, the appropriate bit in the "Characteristics" field of the COFF header is set to indicate that this executable supports virtual addresses greater than 2 gigabytes. This should be used in conjunction with the /3GB or /USERVA=value megabytes switch in the "[operating systems]" section of the BOOT .INI. Otherwise, this bit has no effect. [This option is specific to PE targeted ports of the linker] You can check that the appropriate bit in the COFF header of our current Windows binaries is still be set using dumpbin. i.e: ```powershell dumpbin /headers .\bitcoind.exe FILE HEADER VALUES <snip> 26 characteristics Executable Line numbers stripped Application can handle large (>2GB) addresses ```

2020-01-22Merge #17738: build: remove linking librt for backwards compatibilityWladimir J. van der Laan
f7453dcc0386a4a1162ced1a490c096afa13178a build: remove linking librt for backwards compatibility (fanquake) Pull request description: Now that we require glibc 2.17+, see #17538, we can remove linking librt for backwards compatibility purposes. The `clock_*` functions from librt were merged into glibc as part of the [2.17 release](https://sourceware.org/ml/libc-announce/2012/msg00001.html): * The `clock_*` suite of functions (declared in <time.h>) is now available directly in the main C library. Previously it was necessary to link with -lrt to use these functions. This change has the effect that a single-threaded program that uses a function such as `clock_gettime' (and is not linked with -lrt) will no longer implicitly load the pthreads library at runtime and so will not suffer the overheads associated with multi-thread support in other code such as the C++ runtime library. Note that `librt` is already unused by the RISC-V and AARCH64 binaries as their librts don't export any `clock_*` functions. As an example, you can find a diff of the arm32 vs arm64 librt symbols [here](https://gist.github.com/fanquake/b08cb1f0d14df3133395d7796ebf030c).

2019-12-31build: remove linking librt for backwards compatibilityfanquake
Now that we require glibc 2.17+, #17538, we can remove linking in librt for backwards compatibility purposes. The clock_* functions from librt were merged into glibc as part of the 2.17 release. * The `clock_*' suite of functions (declared in <time.h>) is now available directly in the main C library. Previously it was necessary to link with -lrt to use these functions. This change has the effect that a single-threaded program that uses a function such as `clock_gettime' (and is not linked with -lrt) will no longer implicitly load the pthreads library at runtime and so will not suffer the overheads associated with multi-thread support in other code such as the C++ runtime library. https://sourceware.org/ml/libc-announce/2012/msg00001.html Note that librt is already not linked by the RISC-V and AARCH64 binaries.
