Fix aggrigated uprobes handling
Issue:
When aggrigated uprobe is executed, it never correctly returns
from trampoline_uprobe_handler's retprobe_instance list iteration
if it was called inside anther profiled function.
Solution:
It happened, because break condition was never satisfied: first
time because orig_ret_addr == tramp_addr, all other times because
p, which is pointer to the first uprobe, is not equal to up, which
is other probes related uprobe.
So, this fix removes p and up comparsion as a mistake.

[IMPROVE] remove atomic context from kprobe handler
Changes:
1. Kprobe redesign.
2. Current kprobe state saved in stack (thread context) or
in per_cpu_kpc_data (interrupt context).
for ARM:
In kprobe handler irq is turned on, if kprobe was fired in
non-irq context.
for x86:
Breakpoint is processed in several stages:
1. Save regs and change ip on exec_trampoline().
2. Call handlers in original context.
3. Restore regs and changed instruction processing.

[IMPROVE] Modern kernels (> 3.16) support
Issue:
Great amount of changes in kernel interface, differences
between arch-dependent symbols and definitions.
Solutions:
- Add necessary includes and definitions for
getnstimeofday() (changed interface and declaration location);
- Replace f_dentry with f_path.dentry (f_dentry definition was
removed);
- Replace instruction_pointer() definition with regs->pc for ARM64
(it is casted to unsinged long, so, is treated as simple number);
- Replace hlist_add_after() by version-dependent definition
(now it is hlist_add_behind() in kernel);
- Replace dereference of task->real_start_time with definition
(on recent kernels its type was changed);
- Redefined __get_cpu_var() for modern kernels
(it was removed from kernel);
- Make kernel version-dependent .map/.unmap methods for
pipe_buf_operations;
- Add necessary include for using splice.h;
- Replace strict_strtoul() with kstrtoul() (strict_strtoul()
was removed);
