Factor out evsel__id_hdr_size() so it can be reused. This is needed by perf inject. When injecting events from a guest perf.data file, there is a possibility that the sample ID numbers conflict. To re-write an ID sample, the old one needs to be removed first, which means determining how big it is with evsel__id_hdr_size() and then subtracting that from the event size.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
