//V1.1 20140803 
//  1,delay_us, add parameter equal to 0 to determine, if the parameter is equal to 0, then exit.
//  2, under the modified ucosii, delay_ms function, join the OSLockNesting judgment, entered after a break, also can be used to delay.
//V1.2 20150411  
//  Modify the way OS support to support any OS (not limited to UCOSII and UCOSIII, in theory any OS can support)
//  Add: delay_osrunning/delay_ostickspersec/delay_osintnesting three macro definitions
//  Add: delay_osschedlock/delay_osschedunlock/delay_ostimedly three-function
//V1.3 20150521
