This adds a new mode in ContainedRangeMap which allows existance of
equal ranges. Among those equal ranges, the most recently added range is
the innermost range.
This also adds a function to ContainedRangeMap and
StaticContainedRangeMap to allow users get a vector of entries that
contains given address from innermost to outermost ranges.

The rust-demangle-capi crate hasn't been updated since 2016 and
out-of-date. Instead, Breakpad needs to use C API offered by the
rustc-demangle to demangle Rust symbols.
*** TESTING ***
1) Set up rustc-demangle
> git clone https://github.com/rust-lang/rustc-demangle.git
> cd rustc-demangle
> cargo build -p rustc-demangle-capi --release

Minidumps can contain extended, and compacted extended, contexts to
include xstate data such as the state of the cet registers cetumsr
and cetussp. Previously breakpad would reject dumps with contexts
larger than expected. With this chage, breakpad now accepts and reads
these minidumps. This change does not yet add processing for this
extra data, but will allow any minidumps to be passed on to other
processing tools, or be available for manual inspection.

54d878abcb changed the dump_syms format incompatibly. This must be
redone in a multi-step process: the processor must be made to understand
the old and new formats simultaneously and the processor service must be
rebuilt and run with that update before dump_syms output can change to
use the new format.

Processor shows incorrect source file name if a frame have an inlined
frame and their source files are different.
Consider this example:
FILE 0 /tmp/a.h
FILE 1 /tmp/a.cpp
INLINE_ORIGIN 0 0 foo()
FUNC 1110 a 0 main
INLINE 0 22 0 1110 7
1110 7 3 0
1117 3 23 1
When querying the address 0x1110, we know this line 0x1110 corresponds
to /tmp/a.h line 3 and it's inside a inlined function foo() which is
defined at /tmp/a.h and called at line 22. But we don't know at which
file it's being called at line 22. So, we will get stacks like this:
void foo() /tmp/a.h:3
int main() /tmp/a.h:22
The correct stacks should be this:
void foo() /tmp/a.h:3
int main() /tmp/a.cpp:22
In this change:
1. Remove file_id field for INLINE_ORIGIN record.
2. Add call_site_file_id for INLINE record to represents the file where
this call being inlined.
After adding call_site_file_id to it (as third field), it looks like
this:
FILE 0 /tmp/a.h
FILE 1 /tmp/a.cpp
INLINE_ORIGIN 0 foo()
FUNC 1110 a 0 main
INLINE 0 22 1 0 1110 7
1110 7 3 0
1117 3 23 1
