32b0562375 Add some comments to inet_ntop() 
Endian-ness issues are mind boggling sometimes.  I have been confused by the logic in inet_ntop() a few times so I thought I would add some comments so that I (and others) will understand the endian-ness issues in the future.  No change to logic, only comments changed.

ebdfd16f0f Move gettid() implementation to /libs/libc/unistd 
Move sched/task/task/task_gettid.c to libs/libc/unistd/lib_gettid.c.  gettid() is a dumb wrapper around getpid().  It is wasteful of resources to support TWO systme calls, one for getpid() and one for gettid().  Instead, move gettid() in the C library where it calls the single sysgtem call, getpid().  Much cleaner.

c11c1dc8fd libs/libc/stdio: replace double_t to double 
Modify reason:

When build Nuttx SIM, in x86_64 system:

Compile with gcc option '-m64' (default):
sizeof(double_t) = 8
sizeof(double)   = 8

Compile with gcc option '-mx32':
sizeof(double_t) = 8
sizeof(double)   = 8

Compile with gcc option '-m32':
sizeof(double_t) = 12       // long double
sizeof(double)   = 8

When use '-m32', and print sth. like this:
printf("%f\n", (double)3.0);
SIM will print out: nan

This is because sizeof(double_t) is not equal with double.

Resolve:
replace all double_t to double in libs/libc/stdio.

As a user of '-m32', you should know double_t is one type
long double, and len is 12. And you use use '%lf' to print.
like:
printf("%lf\n", (double_t)3.0);

Currently we don't support '%lf'.

34b34e2d45 Fix: ensure archive files do not carry object files from prior builds 
In some cases, when NuttX configuration changes and this makes the
object list used to build one of the .a libraries change as well,
since the command used to build it is "ar crs" and this simply appends
the list of object files, the library could still include object
files from prior builds. This commit modifies the ARCHIVE macro to
erase the .a file if it already exists.

Since in some cases this behavior was actually expected (object
files from a subdirectory were appended to a library created one
level above) I added a ARCHIVE_ADD which works as ARCHIVE did.

This change should greatly improve behavior of building after
configuration changes.

e249a2f82f Makefile: Fix Make.dep not updated by config changes 
Make.dep file should be updated by .config changed after first make.
There are 2 cases affected for this problem:

 1) Add source files by config symbol
 2) Include header files in #ifdef directive

These 2 cases may not be included in Make.dep and this may prevent the
differential build from working correctly.
