binfmt/ and libs/libc: Make exepath_*() more common:
...
1. Move exepath_*() related code to libc/misc
1. Rename exepath_ to envpath_
2. Rename BINFMT_EXEPATH to LIB_ENVPATH
libs/libc/modlib: Add pre module library symbol table support

binfmt: Add binfmt_initialize(). All binary formats are now registered centrally vs. in board-specific logic. This simplifies the usage of the binfmt subsystem.

This commit extends support for the two-pass build. Its primary purpose is to incorporate source logic generated by applications into the kernel phase of the build.
...
In the two pass build, the application logic is built during the first phase, pass 1. In that phase, the application may generate and install source files in the pass1/directory. The operating system is built during phase 2 of the build. At that time, those source files in the pass1/ directory will be built and incorporated into the kernel address space.
The primary purpose of the pass1/ directory is to such application-generated kernel symbol tables. For an example of the use of this feature, look at apps/examples/module/drivers/Makefile. Kernel symbol tables are needed to support kernel modules. Of course, addition board-specific logic in, say, configs/<board>/src would have to be included to make use of the application-installed symbol tables.

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.

Modules: Add mod_setsymtab to set global symtol table once. Now we can remove symbol table parameters from the insmod call. This will make implementing an NSH insmod command much easier

execv() is a basic system interface. It should not be in libc/ but rather in sched/task. Its symboltable helper logic also belongs in the kernel but belings in binfmt/ with the other symbol table logic
