Fixed issue with gettid() not available with glibc < 2.30.
...
In that case use the syscall interface directly

use own gettid() only for older glibc versions
...
gettid() is provided in glibc since version 2.30. Detect the glibc version
with a macro and only define our own gettid() when glibc version < 2.30.

Do not resolve the decl_file value from other DIEs
...
The other DIEs might be part of another compilation unit, so the
index into the line_table taken from those DIEs might cause an
std::out_of_range exception when used on our line_table.

Port code to build using GCC.

GCC 6 complains with "sorry, unimplemented: non-trivial designated
initializers not supported/" for the original struct initializers.
Rewrite code to clear structs and assign individual members instead.
The designated initializers feature is only part of standard C, not
(at least not yet) part of standard C++.

Use ptrdiff_t for memory offset
...
The type of copy_from_ring_buffer's index argument was inconsistent
between the function's prototype and definition. Emery suggested using
ptrdiff_t rather than size_t, as index represents a memory offset rather
than a size.
We need to include cstddef for ptrdiff_t, so I added that as well.

Sync types of copy_from_ring_buffer and its prototype
...
The prototype declares index as a size_t while the definition declares
it as a uint64_t. If I understand correctly, it's used a memory offset,
so size_t seems preferable.
This causes a build failure with Clang 3.4 on Ubuntu 14.04.3 LTS.
