9ebaabfdde sudo_dso_load: restore original error for AIX on failure.
For AIX, if dlopen() fails we try again with RTLD_MEMBER set
and a default member (shr.o or shr_64.o).  However, if that
also fails, the user will receive a useless error message
that doesn't correspond to the actual problem.  We now retry
the original dlopen() if the fallback to RTLD_MEMBER fails,
which has the effect of restoring the original error message.

e4f08157b6 Fix incorrect SHA384/512 digest calculation.
Resolves an issue where certain message sizes result in an incorrect
checksum. Specifically, when:
(n*8) mod 1024 == 896
where n is the file size in bytes.

e43c964c43 Use sudo_mmap_alloc functions instead of private versions.
We no longer need to keep track of the allocation size.

fccf3c9c56 Add sudo_mmap_{alloc,allocarrary,strdup,free} functions.
These allocate memory via mmap anonymous regions and store the mapped
size immediately before the returned pointer as an unsigned long.
They are intended to be used in cases where malloc(3) and free(3)
are unsuitable due to concerns about corrupting global state in
multi-threaded programs or signal handlers.

e5652fc65a Linux execve(2) allows argv or envp to be NULL.

e5834bd405 Use #include <config.h> not #include "config.h" for consistency.
Otherwise, some compilers may do the wrong thing in a build
dir if there is a config.h file in the source dir too.

b77cbb2e67 Fix building with select (not poll) when fd_set is not defined in sys/types.h.
We can use a void * for the fd_set arrays and just add a cast when
using the FD_SET macros.

f1a697a8ff Use close_range(2) in closefrom() emulation if available.
On Linux, prefer our own closefrom() emulation since the glibc
version may fail if /proc is not present and close_range() is not
supported.  On FreeBSD, closefrom(3) will either call the closefrom
or close_range system call, depending on which is available.

1afce22f7f Use PATH_MAX, not NAME_MAX+1 for the directory entry length.
On some systems, such as Solaris, the max length of a directory
entry is filesystem-dependent.  We could use fpathconf() and
dynamically allocate the name but it is simpler to just use
PATH_MAX here.
