 Adds man:strdupa[3] and man:strndupa[3] functions, which allocate memory for a copy of a string on the stack using man:alloca[3]. This provides a convenient alternative to man:strdup[3] and man:strndup[3] for temporary string copies that are automatically freed when the function returns.

-Adds C23 `<stdbit.h>` header with bit manipulation functions like `stdc_bit_ceil()`, `stdc_bit_width()`, and `stdc_count_ones()`. This provides standard bit operations for C programs.

-The C23 trigonometric functions from the `*pi` family (acospi, acospif etc.) have beed exposed in <math.h>. This provides standard-conforming APIs for applications using these functions.

-The C23 `memalignment()` function has been added to libc, allowing programs to compute pointer alignment. A man page has been included.

 The SONAME of libzfs and libzpool have been bumped to libzfs7 and libzpool7 due to ABI-breaking changes, requiring recompilation of dependent applications.

 Adds libuvmem, a userland port of the man:vmem[9] kernel memory allocator, providing a similar interface for userland applications.

+Partial support for the C23 version of the C Programming language is now available. It will continue to evolve, with complete support anticipated for FreeBSD 16. New features include the `<stdbit.h>` header, the man:memalignment[3] function, updates to the `<limits.h>` and `<stdint.h>` headers including the `_WIDTH` macros and `char8_t`, as well as various other extensions.
