85f727f232 tools: replace INCDIR to Makefile variable 
In the past, header file paths were generated by the incdir command
Now they are generated by concatenating environment variables

In this way, when executing makefile, no shell command will be executed,
it will improve the speed of executing makfile

9af8b740e6 Elf loader: give temporary write access to user .text memory 
When the .elf file is loaded from disk, the kernel must be given write
access to the allocated .text section in the task's address environment.

The access is removed after the elf is loaded and relocations are done.

NOTE:
The reason this works for the ARM implementation, is that the ARM MMU
can be configured to give write access for the privileged mode, but
revoke write access for the user mode.

Regardless, it would be smart to revoke write access even for the
kernel, when the kernel does not need it. This framework allows doing
that, if someone wishes to take up the task.

commit 51490bad55
Author: YAMAMOTO Takashi <yamamoto@midokura.com>
Date:   Wed Apr 14 17:07:39 2021 +0900

    modlib: Implement sh_addralign handling

    I've seen a module with 16 bytes .rodata alignment for xmm operations.
    It was getting SEGV on sim/Linux because of the alignment issue.
    The same module binary seems working fine after applying this patch.

    Also, tested on sim/macOS and esp32 on qemu,
    using a module with an artificially large alignment. (64 bytes)
```

commit 418e11b8b3
Author: YAMAMOTO Takashi <yamamoto@midokura.com>
Date:   Thu Apr 15 11:33:48 2021 +0900

    modlib: Always use separate allocation for text and data

    Pros:

    * Reduce code differences
    * Smaller allocations for !CONFIG_ARCH_USE_MODULE_TEXT

    Cons:

    * Likely to use more memory for !CONFIG_ARCH_USE_MODULE_TEXT in total

    Tested with:

    * sim:module on macOS
    * esp32-devkit:nsh + CONFIG_MODULE on qemu
    * lm3s6965-ek:qemu-protected + CONFIG_EXAMPLES_SOTEST on qemu

c9db653c8d symtabs: improve handling of symbol lookups 
When CONFIG_SYMTAB_ORDEREDBYNAME is selected most code will use
the ordered search function. When it is not selected no code will
use the ordered search function. This change merges the two
functions and varies its behaviour based on the config setting,
such that all callers can simply call the one search function
and get the best behaviour.

An additional configuration option allows leading underscores to
be stripped from symbols being relocated in loaded objects. This
allows toolchains which prefix C symbol with underscores to make
loadable ELF objects.

* Simplify EINTR/ECANCEL error handling

1. Add semaphore uninterruptible wait function
2 .Replace semaphore wait loop with a single uninterruptible wait
3. Replace all sem_xxx to nxsem_xxx

a7fd58c4db Squashed commit of the following: 
many locations:  Change occurences of open() followed by file_detach() to file_open().  Change most non-controversion calls to open() to nx_open().

    fs/inode/fs_fileopen.c:  Flesh out file_open() with some interim, placeholder logic.

    fs/inode/fs_fileopen.c:  Add a framework for a file_open() implementation (no real logic in place yet).

    fs/vfs/fs_open.c:  Add nx_open() which is the same as open() except that it does not create a cancellation point nor does it modify the errno variable.
