Add testcase 'sched_getattr01' to test sched_getattr function
Signed-off-by: Cui Bixuan <cuibixuan@huawei.com>
---
V3: * Include stdint.h and inttypes.h to get the int32_t and uint64_t types
defined and to get PRIu64 defined;
* Add "sched_getattr01 sched_getattr01" to runtest/syscalls;
* Change "-lpthread" to "-pthread" in testcases/kernel/syscalls/sched_getattr/Makefile;
* Use PRIu64 to print uint64_t;
V2: * Add the test to syscalls/sched_getattr and rename it to "sched_getattr01";
* Change "LDLIBS" to "CFLAGS" in sched_getattr/Makefile;
* Delete "#define gettid() ..." which is not need in case;
* Add "__NR_sched_setattr" and "__NR_sched_getattr" to arm.in,i386.in,x86_64.in
in testcases/kernel/include/;
* Create lapi/sched.h and add "struct sched_attr" and "sched_setattr", "sched_getattr"
to it;
* uint32_t/uint64_t/int32_t instead of __u32/__u64/__s32;
* Delete printf() in case and change "TFAIL" to "TFAIL | TERRNO" in tst_brkm();
* define RUNTIME_VAL PERIOD_VAL DEADLINE_VAL for comparing and split one if to three ifs;
* Delete sleep(1) and tst_resm(TPASS,..) in main.
