Add a parser for /proc/modules style files, ModMap. /proc/modules contains information about memory ranges of modules. We need such information in order to understand which module a given kernel address belongs to. On top of just parsing contents, objects of this type provide the means for querying the module name that an address belongs to, if any. Signed-off-by: Daniel Müller <deso@posteo.net>
Add logic for parsing depmod binary files. These files basically contain a search tree for efficiently looking up module paths (relative to a base directory) given a module name. Making such a lookup possible enables the loading of module binaries, which may contain DWARF debug information for symbolization that resolves source code information (as opposed to /proc/kallsyms, which only has limited function granularity for addresses).
