Implement the *allocx() API. Implement the *allocx() API, which is a successor to the *allocm() API. The *allocx() functions are slightly simpler to use because they have fewer parameters, they directly return the results of primary interest, and mallocx()/rallocx() avoid the strict aliasing pitfall that allocm()/rallocx() share with posix_memalign(). The following code violates strict aliasing rules: foo_t *foo; allocm((void **)&foo, NULL, 42, 0); whereas the following is safe: foo_t *foo; void *p; allocm(&p, NULL, 42, 0); foo = (foo_t *)p; mallocx() does not have this problem: foo_t *foo = (foo_t *)mallocx(42, 0);

Implement the *allocx() API. Implement the *allocx() API, which is a successor to the *allocm() API. The *allocx() functions are slightly simpler to use because they have fewer parameters, they directly return the results of primary interest, and mallocx()/rallocx() avoid the strict aliasing pitfall that allocm()/rallocx() share with posix_memalign(). The following code violates strict aliasing rules: foo_t *foo; allocm((void **)&foo, NULL, 42, 0); whereas the following is safe: foo_t *foo; void *p; allocm(&p, NULL, 42, 0); foo = (foo_t *)p; mallocx() does not have this problem: foo_t *foo = (foo_t *)mallocx(42, 0);

Clean compilation -Wextra Before this commit jemalloc produced many warnings when compiled with -Wextra with both Clang and GCC. This commit fixes the issues raised by these warnings or suppresses them if they were spurious at least for the Clang and GCC versions covered by CI. This commit: * adds `JEMALLOC_DIAGNOSTIC` macros: `JEMALLOC_DIAGNOSTIC_{PUSH,POP}` are used to modify the stack of enabled diagnostics. The `JEMALLOC_DIAGNOSTIC_IGNORE_...` macros are used to ignore a concrete diagnostic. * adds `JEMALLOC_FALLTHROUGH` macro to explicitly state that falling through `case` labels in a `switch` statement is intended * Removes all UNUSED annotations on function parameters. The warning -Wunused-parameter is now disabled globally in `jemalloc_internal_macros.h` for all translation units that include that header. It is never re-enabled since that header cannot be included by users. * locally suppresses some -Wextra diagnostics: * `-Wmissing-field-initializer` is buggy in older Clang and GCC versions, where it does not understanding that, in C, `= {0}` is a common C idiom to initialize a struct to zero * `-Wtype-bounds` is suppressed in a particular situation where a generic macro, used in multiple different places, compares an unsigned integer for smaller than zero, which is always true. * `-Walloc-larger-than-size=` diagnostics warn when an allocation function is called with a size that is too large (out-of-range). These are suppressed in the parts of the tests where `jemalloc` explicitly does this to test that the allocation functions fail properly. * adds a new CI build bot that runs the log unit test on CI. Closes #1196 .

Clean compilation -Wextra Before this commit jemalloc produced many warnings when compiled with -Wextra with both Clang and GCC. This commit fixes the issues raised by these warnings or suppresses them if they were spurious at least for the Clang and GCC versions covered by CI. This commit: * adds `JEMALLOC_DIAGNOSTIC` macros: `JEMALLOC_DIAGNOSTIC_{PUSH,POP}` are used to modify the stack of enabled diagnostics. The `JEMALLOC_DIAGNOSTIC_IGNORE_...` macros are used to ignore a concrete diagnostic. * adds `JEMALLOC_FALLTHROUGH` macro to explicitly state that falling through `case` labels in a `switch` statement is intended * Removes all UNUSED annotations on function parameters. The warning -Wunused-parameter is now disabled globally in `jemalloc_internal_macros.h` for all translation units that include that header. It is never re-enabled since that header cannot be included by users. * locally suppresses some -Wextra diagnostics: * `-Wmissing-field-initializer` is buggy in older Clang and GCC versions, where it does not understanding that, in C, `= {0}` is a common C idiom to initialize a struct to zero * `-Wtype-bounds` is suppressed in a particular situation where a generic macro, used in multiple different places, compares an unsigned integer for smaller than zero, which is always true. * `-Walloc-larger-than-size=` diagnostics warn when an allocation function is called with a size that is too large (out-of-range). These are suppressed in the parts of the tests where `jemalloc` explicitly does this to test that the allocation functions fail properly. * adds a new CI build bot that runs the log unit test on CI. Closes #1196 .

Implement the *allocx() API. Implement the *allocx() API, which is a successor to the *allocm() API. The *allocx() functions are slightly simpler to use because they have fewer parameters, they directly return the results of primary interest, and mallocx()/rallocx() avoid the strict aliasing pitfall that allocm()/rallocx() share with posix_memalign(). The following code violates strict aliasing rules: foo_t *foo; allocm((void **)&foo, NULL, 42, 0); whereas the following is safe: foo_t *foo; void *p; allocm(&p, NULL, 42, 0); foo = (foo_t *)p; mallocx() does not have this problem: foo_t *foo = (foo_t *)mallocx(42, 0);
