contrib/xxhash: update to latest xxHash (0.6.5)

2018-08-16T04:06:13+00:00

Update to latest xxHash, which is supposed to faster with small keys.

Specifically, updated to 3064d42e7d74b0921bdd1818395d9cb37bb8976a,
which is a bit higher than 0.6.5.

Compiled hopefully with namespace (XXH_NAMESPACE=GF_),
which allows to use XXH() funcs with no fear they'll 'leak'
from our library.

Only compile tested!

xxhsum is modified to display messages which was conflicting
with regression tests (TAP harness). So modified the
gfid2path_fuse.t and gfid2path_nfs.t to adhere to that.

tests: merge stdout and stderr output

2018-01-30T05:59:09+00:00

Add -m argument to 'prove' command-line.

Fix xxhsum.c debugging output to keep 'prove' happy.

Modifications to source:
------------------------
Following functions and data types got 'GF_' prefix
as below to avoid any form of name collisions in future.

    ---- Functions ----
    GF_XXH_versionNumber
    GF_XXH32
    GF_XXH32_createState
    GF_XXH32_freeState
    GF_XXH32_copyState
    GF_XXH32_reset
    GF_XXH32_update
    GF_XXH32_digest
    GF_XXH32_canonicalFromHash

    GF_XXH64_update
    GF_XXH64_digest
    GF_XXH64_canonicalFromHash
    GF_XXH64_hashFromCanonical

    ---- Data Types ----
    GF_XXH_errorcode
    GF_XXH32_state_t*
    GF_XXH32_canonical_t*
    GF_XXH32_hash_t
    GF_XXH64_state_t*
    GF_XXH64_canonical_t*
    GF_XXH64_hash_t

It is linked with libglusterfs.so. A wrapper
funtion is also added for the easy usage in
common-utils.c.

xxhash can be used for the all the usecases where
a faster non-cryptographic hash is required.
gfid to path infra would be using this for now.

NOTE:
----
The gluster coding guidelines check is ignored
as maintaining it further would be difficult.
