env_dup: Fix copying of env between address environments
...
If address environments are in use, it is not possible to simply
memcpy from from one process to another. The current implementation
of env_dup does precisely this and thus, it fails at once when it is
attempted between two user processes.
The solution is to use the kernel's heap as an intermediate buffer.
This is a simple, effective and common way to do a fork().
Obviously this is not needed for kernel processes.

This commit moves shared builtin information out of binfmt/libbuiltin and into libs/libc/builtin where it can be shared. This should permit builtin application in the PROTECTED build where binfmt/libbuiltin is not available in user space.
...
Squashed commit of the following:
Correct some additional compile-related issues.
Move include/nuttx/binfmt/builtin.h to include/nuttx/lib/builtin.h. Move apps/builtin/lib_builtin_forindex.c to libs/libc/builtin/lib_builtin_forindex.c.
Move binfmt/libbuiltin to libs/libc/builtin. There are calls made directly from apps/nshlib into this logic and hence, must be part of a library that can be shared between the OS and applications.

binfmt/ and sched/group: Re-architect the way that loadable ELF or NXFLAT modules are unloaded. Memory resources must be recovered when the task loaded into memory exits. The originmal implementatino used the death-of-child SIGCHLD signal to perform the unload. There are several problems with this: It is overly complex, it requires that the parent task stay resident while the loaded task runs, and it has fatal logic flaws in the protected and kernel model builds because the user signal handler attempts to run in the kernel address space. This commit corrects with using a mindlessly simply BINFMT callback when the task exits.
