c85eb4a59b avoid dump_syms crashing if selected arch is not found
https://crrev.com/c/3327644 introduced the ability for dump_syms to
operate on in memory data, which has the consequence of not going
through the same input validation as the dump_syms cli tool. In certain
cases, it is possible that architecture info can't be reliably
determined, e.g. new architectures that breakpad is unware of. In that
case, dump_syms should avoid crashing when calling ReadSymbolData and
return false instead.

link different implementations of FileID. This change puts the
different implementations into separate namespaces to avoid the

file system. This change allows dump_syms to operate on the contents of
a file that has already been read into memory. This is useful in a
server context where the file does not exist on the local file system.

38ee0be4d1 Update Rust demangling to use rustc-demangle
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out-of-date.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

2) Breakpad

> ./configure --with-rustc-demangle=<path to rustc-demangle>
> make check src/common/dward_cu_to_module

dfcb7b6799 Revert "Fix incorrect source file name for inlined frames"
This reverts commit 54d878abcb.

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.

54d878abcb Fix incorrect source file name for inlined frames
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

7ba29f4a36 Mitigate upload failure when app is backgrounded.
iOS closes an app’s network connections when the app is backgrounded. This can cause an in-progress upload request to fail. We can mitigate this by requesting additional background execution time using the `UIApplication` background task APIs.

f7428bc397 Fix macos_dump_syms when __eh_frame is included in the dSYM file.
macho_reader assumes that every section in a segment exists, or none of the
sections exist in the file (for dSYM files).

https://reviews.llvm.org/D94460?id=315965 added __eh_frame section to the
__TEXT segments in dSYM files. All the other sections are removed, but still
have non-zero size in the header. macho_reader only looks at `fileoff` and
`filesize` fields to determine the size of the segment, but it looks at `addr`
and `size` to determine the size of the section, therefore it determines that
the sections would not fit in the segment and refused to parse the file.

In this case the removed sections all have offset == 0. Ignore such cases.

275e6d46a4 Make forward reference DIEs cross compilation units.
Before this change, forward_ref_die_to_func is always empty.
Because forward reference DIEs could cross compilation units,
forward_ref_die_to_func is moved into FilePrivate.
By using "grep "name omitted" sym | wc -l", the number of functions
with no name is reduced from 26951 to 203 if forward reference only is
allowed within CU. It's reduced from 203 to 6 if crossing compilation
units is allowed.

If there is an address index reference to .debug_addr section before

An example could be DW_AT_loc_pc occurs before DW_AT_addr_base.
