Tim Zhang 0f76570677 Avoid exception caused by cgroup writeback feature 
The cgroup writeback feature requires cooperation
between memcgs and blkcgs.
To avoid exceptions, we should add_task for blkcg before
memcg(push BlkIo before Mem).

Tim Zhang 567cdb43b3 Use Option as resource fields, remove the update switch: update_values 
Use idiomatic Option::None to represent optional fields.
This enables updates where not all fields need to be specified.

Tim Zhang 0c18b0855e Support customized attributes for CpuController and MemController 
Customized attributes are useful for customized kernels.

Usage:
	let resource = &mut cgroups::Resources::default();
	resource.cpu.attrs.insert("cpu.cfs_init_buffer_us", "10".to_string());
	// apply here

zhanghj cd7e737149 lib: fix compiling error for type i8 in aarch64 environment 
c_char is equal to i8 on x86, but it is equal to u8 on arm arch,
so we need to use type c_char instead of i8 to avoid compiling error.

Fixes: #9
