[PATCH v1 0/6] gdb: introduce file_reader_t to read procfs files

[Matthieu Longo <matthieu.longo@arm.com>]

Those patches were extracted from a previous patch series [1].
Patches 1 and 2 are prerequisites to the next patches.
Patch 3 introduces class file_reader_t, and patches 4, 5, and 5 migrates existing code to use this new class.

Changes diff against [1]:
- remove reimplementation of std::replace, and use std::replace for gdb::ranges::replace.
- addressed comments from Christina Schimpe and Chirstina Joos regarding the interface of class file_reader_t.
- fix the implementation of extract_string_view_from_buffer after Luis found bugs in the previous implementation.

This patch series depends on [2].
