Fixed PR 11078. Changed code to avoided procfs race condition.
* runtime/procfs.c: Allow STP_MAX_PROCFS_FILES define to be overridden.
(_stp_create_procfs): Calls proc_create() instead of create_proc_entry()
to avoid a race condition.
* runtime/procfs-probes.c: New file containing procfs probe support
routines.
* tapset-procfs.cxx (procfs_derived_probe::join_group): Update struct
_stp_procfs_data definition.
(procfs_derived_probe::emit_module_decls): Include procfs-probes.c,
which is where the definition of struct stap_procfs_probe exists.
Update generated routines to read/write procfs data.
(procfs_derived_probe_group::emit_module_init): Pass file_operations
argument to _stp_create_procfs(). Initialize mutex.
(procfs_var_expanding_visitor::visit_target_symbol): Update generated
code.
