Currently NSH prompt is defined at build time, thus improper for AMP cases
where the same NSH binary is used on different nodes as the same NSH prompt
shows on all nodes.
This patch attempts to support runtime prompt string population from ordered
sources:
- the environment variable defined by NSH_PROMPT_ENV plus suffix
- the NSH_PROMPT_STRING
- the HOSTNAME plus suffix
The suffix is defined by NSH_PROMPT_SUFFIX so that to clearly separate the
command inputs.
Changes in `nshlib/`
- Kconfig: add configs NSH_PROMPT_MAX/ENV/SUFFIX etc
- nsh.h: adjust g_nshprompt defs, add nsh_update_prompt
- nsh_parse.c relocate g_nshpromt to nsh_prompt.c
- nsh_init.c revise to use nsh_update_prompt once
- nsh_session.c revise to use methods in nsh_prompt.c
- Makefile add nsh_prompt.c
- CMakeLists.txt add nsh_prompt.c
New additions in `nshlib/`
- nsh_prompt.c prompt related data structures and methods.

Here are some offenders: examples/cc3000/shell.c, examples/nsh/nsh_main.c, examples/nxterm/nxterm_main.c, and examples/pty_test/pty_test.c. It is possible that for some of those, that represents the first call to nsh_consolemain(). But probably not.
To give other initialization options, I added nsh_consolechild() which is identical to nsh_consolemain() other than it omits all of the one-time initialization. Of course, you would not get the result that you wanted if nsh_consolechild() were called without nsh_consolemain().
