Log:
import 2984: alter should be incremental

Summary:
import patch for HBASE-2984.

The patch had some minor bugs with compression and bloom settings. I have fixed
those issue in this diff, and also update the public JIRA.

Test Plan:
hbase(main):005:0> create 't', {NAME => 'cf1', VERSIONS => 100, BLOOMFILTER =>
'ROWCOL', COMPRESSION => 'LZO'}
0 row(s) in 1.1430 seconds

hbase(main):006:0> disable 't'
0 row(s) in 1.0690 seconds

hbase(main):007:0> describe 't'
DESCRIPTION

 ENABLED

 {NAME => 't', FAMILIES => [{NAME => 'cf1', BLOOMFILTER => 'ROWCOL',
REPLICATION_SCOPE => '0', VERSIONS => '100', COMPRESSION => 'LZO', TTL =>
'2147483647', BLOC false

 KSIZE => '65536', IN_MEMORY => 'false', BLOCKCACHE => 'true'}]}

1 row(s) in 0.0430 seconds

hbase(main):008:0> alter 't', {NAME => 'cf1', VERSIONS => 50}
0 row(s) in 0.0630 seconds

hbase(main):009:0> describe 't'
