filestore: avoid open write close sequence
Current file storing approach is using a open file, write data,
close file logic. If this technic is fixing the problem of getting
too much open files in Suricata it is not optimal.
Test on a loop shows that open, write, close on a single file is
two time slower than a single open, loop of write, close.
This patch updates the logic by storing the fd in the File structure.
This is done for a certain number of files. If this amount is exceeded
then the previous logic is used.
This patch also adds two counters. First is the number of
currently open files. The second one is the number of time
the open, write, close sequence has been used due to too much
open files.
In EVE, the entries are:
stats {file_store: {"open_files_max_hit":0,"open_files":5}}
