socketpair: add `eventfd` and use `SOCK_NONBLOCK` for `socketpair()` Currently, we use `pipe` for `wakeup_create`, which requires ***two*** file descriptors. Furthermore, given its complexity inside, `pipe` is a bit heavyweight for just a simple event wait/notify mechanism. `eventfd` would be a more suitable solution for this kind of scenario, kernel also advocates for developers to use `eventfd` instead of `pipe` in some simple use cases: Applications can use an eventfd file descriptor instead of a pipe (see pipe(2) in all cases where a pipe is used simply to signal events. The kernel overhead of an eventfd file descriptor is much lower than that of a pipe, and only one file descriptor is required (versus the two required for a pipe). This change adds the new backend of `eventfd` for `wakeup_create` and uses it where available, eliminating the overhead of `pipe`. Also, it optimizes the `wakeup_create` to eliminate the system calls that make file descriptors non-blocking by moving the logic of setting non-blocking flags on file descriptors to `socketpair.c` and using `SOCK_NONBLOCK` for `socketpair(2)`, `EFD_NONBLOCK` for `eventfd(2)`.

build: delete `HAVE_STDINT_H` and `HAVE_INTTYPES_H` We use `stdint.h` unconditionally in all places except one. These uses are imposed by external dependencies / features. nghttp2, quic, wolfSSL and `HAVE_MACH_ABSOLUTE_TIME` do require this C99 header. It means that any of these features make curl require a C99 compiler. (In case of MSVC, this means Visual Studio 2010 or newer.) This patch changes the single use of `stdint.h` guarded by `HAVE_STDINT_H` to use `stdint.h` unconditionally. Also stop using `inttypes.h` as an alternative there. `HAVE_INTTYPES_H` wasn't used anywhere else, allowing to delete this feature check as well. Closes #12275

cmake: pre-fill rest of detection values for Windows The goal of this patch is to avoid unnecessary feature detection work when doing Windows builds with CMake. Do this by pre-filling well-known detection results for Windows and specifically for mingw-w64 and MSVC compilers. Also limit feature checks to platforms where the results are actually used. Drop a few redundant ones. And some tidying up. - pre-fill remaining detection values in Windows CMake builds. Based on actual detection results observed in CI runs, preceding similar work over libssh2 and matching up values with `lib/config-win32.h`. This brings down CMake configuration time from 58 to 14 seconds on the same local machine. On AppVeyor CI this translates to: - 128 seconds -> 50 seconds VS2022 MSVC with OpenSSL (per CMake job): https://ci.appveyor.com/project/curlorg/curl/builds/48208419/job/4gw66ecrjpy7necb#L296 https://ci.appveyor.com/project/curlorg/curl/builds/48217440/job/8m4fwrr2fe249uo8#L186 - 62 seconds -> 16 seconds VS2017 MINGW (per CMake job): https://ci.appveyor.com/project/curlorg/curl/builds/48208419/job/s1y8q5ivlcs7ub29?fullLog=true#L290 https://ci.appveyor.com/project/curlorg/curl/builds/48217440/job/pchpxyjsyc9kl13a?fullLog=true#L194 The formula is about 1-3 seconds delay for each detection. Almost all of these trigger a full compile-link cycle behind the scenes, slow even today, both cross and native, mingw-w64 and apparently MSVC too. Enabling .map files or other custom build features slows it down further. (Similar is expected for autotools configure.) - stop detecting `idn2.h` if idn2 was deselected. autotools does this. - stop detecting `idn2.h` if idn2 was not found. This deviates from autotools. Source code requires both header and lib, so this is still correct, but faster. - limit `ADDRESS_FAMILY` detection to Windows. - normalize `HAVE_WIN32_WINNT` value to lowercase `0x0a12` format. - pre-fill `HAVE_WIN32_WINNT`-dependent detection results. Saving 4 (slow) feature-detections in most builds: `getaddrinfo`, `freeaddrinfo`, `inet_ntop`, `inet_pton` - fix pre-filled `HAVE_SYS_TIME_H`, `HAVE_SYS_PARAM_H`, `HAVE_GETTIMEOFDAY` for mingw-w64. Luckily this do not change build results, as `WIN32` took priority over `HAVE_GETTIMEOFDAY` with the current source code. - limit `HAVE_CLOCK_GETTIME_MONOTONIC_RAW` and `HAVE_CLOCK_GETTIME_MONOTONIC` detections to non-Windows. We're not using these in the source code for Windows. - reduce compiler warning noise in CMake internal logs: - fix to include `winsock2.h` before `windows.h`. Apply it to autotools test snippets too. - delete previous `-D_WINSOCKAPI_=` hack that aimed to fix the above. - cleanup `CMake/CurlTests.c` to emit less warnings. - delete redundant `HAVE_MACRO_SIGSETJMP` feature check. It was the same check as `HAVE_SIGSETJMP`. - delete 'experimental' marking from `CURL_USE_OPENSSL`. - show CMake version via `CMakeLists.txt`. Credit to the `zlib-ng` project for the idea: https://github.com/zlib-ng/zlib-ng/blob/61e181c8ae93dbf56040336179c9954078bd1399/CMakeLists.txt#L7 - make `CMake/CurlTests.c` pass `checksrc`. - `CMake/WindowsCache.cmake` tidy-ups. - replace `WIN32` guard with `_WIN32` in `CMake/CurlTests.c`.

build: streamline non-UWP wincrypt detections - with CMake, use the variable `WINDOWS_STORE` to detect an UWP build and disable our non-UWP-compatible use the Windows crypto API. This allows to drop two dynamic feature checks. `WINDOWS_STORE` is true when invoking CMake with `CMAKE_SYSTEM_NAME` == `WindowsStore`. Introduced in CMake v3.1. Ref: https://cmake.org/cmake/help/latest/variable/WINDOWS_STORE.html - with autotools, drop the separate feature check for `wincrypt.h`. On one hand this header has been present for long (even Borland C 5.5 had it from year 2000), on the other we used the check result solely to enable another check for certain crypto functions. This fails anyway with the header not present. We save one dynamic feature check at the configure stage. Reviewed-by: Marcel Raad Closes #11657

lib: sync guard for Curl_getaddrinfo_ex() definition and use `Curl_getaddrinfo_ex()` gets _defined_ with `HAVE_GETADDRINFO` set. But, `hostip4.c` _used_ it with `HAVE_GETADDRINFO_THREADSAFE` set alone. It meant a build with the latter, but without the former flag could result in calling this function but not defining it, and failing to link. Patch this by adding an extra check for `HAVE_GETATTRINFO` around the call. Before this patch, build systems prevented this condition. Now they don't need to. While here, simplify the related CMake logic on Windows by setting `HAVE_GETADDRINFO_THREADSAFE` to the detection result of `HAVE_GETADDRINFO`. This expresses the following intent clearer than the previous patch and keeps the logic in a single block of code: When we have `getaddrinfo()` on Windows, it's always threadsafe.

tidy-up: process.h detection and use This patch aims to cleanup the use of `process.h` header and the macro `HAVE_PROCESS_H` associated with it. - `process.h` is always available on Windows. In curl, it is required only for `_beginthreadex()` in `lib/curl_threads.c`. - `process.h` is also available in MS-DOS. In curl, its only use was in `lib/smb.c` for `getpid()`. But `getpid()` is in fact declared by `unistd.h`, which is always enabled via `lib/config-dos.h`. So the header is not necessary. - `HAVE_PROCESS_H` was detected by CMake, forced to 1 on Windows and left to real detection for other platforms. It was also set to always-on in `lib/config-win32.h` and `lib/config-dos.h`. In autotools builds, there was no detection and the macro was never set. Based on these observations, in this patch we: - Rework Windows `getpid` logic in `lib/smb.c` to always use the equivalent direct Win32 API function `GetCurrentProcessId()`, as we already did for Windows UWP apps. This makes `process.h` unnecessary here on Windows. - Stop #including `process.h` into files where it was not necessary. This is everywhere, except `lib/curl_threads.c`. > Strangely enough, `lib/curl_threads.c` compiled fine with autotools > because `process.h` is also indirecty included via `unistd.h`. This > might have been broken in autotools MSVC builds, where the latter > header is missing. - Delete all remaining `HAVE_PROCESS_H` feature guards, for they were unnecessary. - Delete `HAVE_PROCESS_H` detection from CMake and predefined values from `lib/config-*.h` headers.
