[LTP] [PATCH 0/4] optimize quotactl code

[Yang Xu]

Hello

I cleanup the quotactl code. 
Remove useless ltp-xfs_quota.m4 and rewriting ltp_quota.m4. Also add Q_GETNEXTQUOTA and Q_XGETQSTATV flag
test. 

The build travis-ci log as below:
https://travis-ci.org/xuyang0410/ltp/jobs/600658655

It build failed on some linux distributions because quotactl function return value is different. In sys/quota.h it is int,
in linux/quota.h is long. I use linux/quota.h because I want to use if_nextdqblk struct to test Q_GETNEXQUOTA
flag. I doubt whether I need to fix the build error by custom define the if_nextdqblk struct or it is a old kernel
uncompatible bug I don't need to fix.

ps:
I am writing quotactl testcases about project quota for #529. 
I will send it tomorrow.
