[bsp][c28x] add support to not disable global interrupt in context-switch to enable zero-latency isr for critical interrupts.

The RT_ASSERT(obj != object) line is only compiled for debug mode.
But the rt_enter/exit_critical causes the compiler not to optimize
at least these 2 calls, even if it could optimize out the whole loop,
because the rt_list_entry function has no side effect, and RT_ASSET
is a no-operation in release mode. So this patch fixes this:
- no warnings anymore
- better speed in release mode

* [ulog] Fix the problem that the terminal cannot input

* [mem] Fix NULL pointer access

* [fix] Fix simulator compilation warnings

* Update bsp/simulator/rtconfig_project.h

版本控制规范：https://semver.org/

目前的版本子号不是很规范，其中RT_VERSION甚至和VS那边造成了冲突
```c
/* RT-Thread version information */
#define RT_VERSION                      4L              /**< major version number */
#define RT_SUBVERSION                   1L              /**< minor version number */
#define RT_REVISION                     1L              /**< revise version number */
```

参考ESP32：
```c
/** Major version number (X.x.x) */
#define ESP_ARDUINO_VERSION_MAJOR   2
/** Minor version number (x.X.x) */
#define ESP_ARDUINO_VERSION_MINOR   0
/** Patch version number (x.x.X) */
#define ESP_ARDUINO_VERSION_PATCH   3
```

建议改成：
```c
/* Major version number (X.x.x) */
#define RT_VERSION_MAJOR   4
/* Minor version number (x.X.x) */
#define RT_VERSION_MINOR   2
/* Patch version number (x.x.X) */
#define RT_VERSION_PATCH   0
```

* 增加printf格式2进制和8进制，RT_KPRINTF_USING_LONGLONG 和 RT_PRINTF_SPECIAL 做了相应处理

解决 tms320f28379d bsp 启动的问题。主要改动如下。

修正context.s中汇编代码错误。在旧版的代码中，操作数为32位而汇编命令却使用了针对16位数据的命令MOV，导致程序在某些情况无法正常启动线程。
由于C28x的平台下，SP只支持16bit寻址，所以用于线程空间存放的heap以及ebss段都需要放在低16位的空间，针对这个问题修改了CMD文件。此外还增加基于CMD文件基于RAM的支持，方便调试。
新增rtdef.h中RT_SECTION，RT_USED，ALIGN和RT_WEAK的定义。旧版bsp中这些定义为空，导致INIT_EXPORT注册的函数失效。
修改程序启动代码，在程序入口直接调用原生启动代码
以上改动在LAUNCHXL-F28379D 通过了测试。

main线程栈指定对齐字节数

For compatibility with 16bit addressing 32bit CPU (e.g. TI C28x).

* compile_ok

Issues fixed:
(1) update .config: select FINSH_USING_SYMTAB
(2) add rt_size_t in rtconfig_project.h
(3) fix finsh problems of using sym table
(4) update .project to include ipc source codes.
Todo list:
(1) automate the build source selection of ccs and reconcile it with scons

* change compiler

* msh can run now

the key step is to swap the order of rt_interrupt_nest -- and RT_OBJECT_HOOK_CALL(rt_interrupt_leave_hook,()) in irq.c. This is an improvised solution and an issue has been raised.

* Update 2837x_FLASH_lnk_cpu1.cmd

The original one is also fine. Just to make it more rigorous since FSymTab is in data section.

* update readme.md

Complier selection and maintainer update.
