As we'll also hook into the syscalls:sys_exit_SYSCALL for which there are enter hooks. This way we'll be able to iterate the ELF file for the eBPF program, find the syscalls that have hooks and filter them out from the general raw_syscalls:sys_{enter,exit} tracepoint for not-yet-augmented (the ones with pointer arguments not yet being attached to the usual syscalls tracepoint payload) and non augmentable syscalls (syscalls without pointer arguments).

Reflecting the fact that it now augments more than syscalls:sys_enter_SYSCALL tracepoints that have filename strings as args. Also mention how the extra data is handled by the by now modified 'perf trace' beautifiers, that will use special "augmented" beautifiers when extra data is found after the expected syscall enter/exit tracepoints.

Create auxiliary trace data log files when invoked with option --itrace=d as in: [root@s35lp76 perf] perf report -i perf.data.aux1 --stdio --itrace=d perf report creates several data files in the current directory named aux.smp.## where ## is a 2 digit hex number with leading zeros representing the CPU number this trace data was recorded from. The file contents is binary and contains the CPU-Measurement Sampling Data Blocks (SDBs). The directory to save the auxiliary trace buffer can be changed using the perf config file and command. Specify section 'auxtrace' keyword 'dumpdir' and assign it a valid directory name. If the directory does not exist or has the wrong file type, the current directory is used.

Its a 'struct sockaddr' pointer, augment it with the same beautifier as for 'connect' and 'bind', that all receive from userspace that pointer.

So that we don't have to define sockaddr_storage in the augmented_syscalls.c bpf example when hooking into syscalls needing it, idea is to mimic the system headers. Eventually we probably need to have sys/socket.h, etc. Start by having at least linux/socket.h.
