Add more operation analysis, combine with deletes and inserts variables.

[linD026]

Add more operation analysis, combine with deletes and inserts variables.
And Using the preprocessor to decide the analysis being set or not.

For example:

retry     : 187
contains  : 0
traversal : 21028166
fail      : 0
del       : 0
ins       : 0
load      : 63167962
store     : 4096
deletes   : 4098
inserts   : 4098
"retry"    is the number of retries in the __list_find function.
"contains" is the number of wait-free contains in the __list_find function that curr pointer pointed.
"traversal"is the number of list element traversal in the __list_find function.
"fail"     is the number of CAS() failures.
"del"      is the number of list_delete operation failed and restart again.
"ins"      is the number of list_insert operation failed and restart again.
"deletes"  is the number of linked list elements deleted.
"inserts"  is the number of linked list elements created.
"load"     is the number of atomic_load operation in list_delete, list_insert and __list_find.
"store"    is the number of atomic_store operation in list_delete, list_insert and __list_find.

The following are the new variables to record the operations:
rtry is the number of retries in the __list_find function.
cons is the number of wait-free contains in the __list_find function that curr pointer pointed.
trav is the number of list element traversal in the __list_find function.
fail is the number of CAS() failures.
del is the number of list_delete operation failed and restart again.
ins is the number of list_insert operation failed and restart again.

Because the atomic_fetch_add will be only used with recording the operation state in related function in linked list, I think ops just mark the meaning of ATOMIC_FETCH_ADD is doing. Also there is the reason why the body was empty.

[jserv]

However, macro ATOMIC_FETCH_ADD was not consistent if it turns into an empty one.

[linD026]

I only change ATOMIC_FETCH ADD into TRACE_ATOMIC_FETCH_ADD for distinguishing record operation from normal. There are other solutions, but I think this is the best one because it does not cost more memory or if-else statement.

[jserv]

Use wrapper macro for runtime stat initialization/hook.

[jserv]

Rewrite macro TRACE as following:

do { /* nothing involved */ } while (0)

The names are from A more Pragmatic Implementation of the Lock-free, Ordered, Linked List.
traversal and others are intelligible I will change it.

Thank @linD026 for the great work!
