Fix the RLIM_INFINITY and RLIM64_INFINITY constants on alpha to match the kernel one and all other architectures. Change the getrlimit, getrlimit64, setrlimit, setrlimit64 into old compat symbols, and provide the Linux generic functions as GLIBC_2_27 version. Changelog: * sysdeps/unix/sysv/linux/getrlimit64.c [USE_VERSIONED_RLIMIT]: Do not define getrlimit and getrlimit64 as weak aliases of __getrlimit64. Define __GI_getrlimit64 as weak alias of __getrlimit64. [__RLIM_T_MATCHES_RLIM64_T]: Do not redefine SHLIB_COMPAT, use #elif instead. * sysdeps/unix/sysv/linux/setrlimit64.c [USE_VERSIONED_RLIMIT]: Do not define setrlimit and setrlimit64 as weak aliases of __setrlimit64. * sysdeps/unix/sysv/linux/alpha/bits/resource.h (RLIM_INFINITY, RLIM64_INFINITY): Fix values to match the kernel ones. * sysdeps/unix/sysv/linux/alpha/getrlimit64.c: Define USE_VERSIONED_RLIMIT. Rename __getrlimit64 into __old_getrlimit64 and provide it as getrlimit@@GLIBC_2_0 and getrlimit64@@GLIBC_2_1. Add a __getrlimit64 function and provide it as getrlimit@@GLIBC_2_27 and getrlimit64@@GLIBC_2_27. * sysdeps/unix/sysv/linux/alpha/setrlimit64.c: Ditto with setrlimit and setrlimit64. * sysdeps/unix/sysv/linux/alpha/libc.abilist (GLIBC_2.27): Add getrlimit, setrlimit, getrlimit64 and setrlimit64. * sysdeps/unix/sysv/linux/alpha/Versions (libc): Add getrlimit, setrlimit, getrlimit64 and setrlimit64.
