Since we now have mi_runto_main which is like runto_main, eliminate
mi_run_to_main, in favor of a new MI clean_restart counterpart --
mi_clean_restart -- and mi_runto_main.
This makes MI testcases look a bit more like CLI testcases.
gdb/testsuite/ChangeLog:
* lib/mi-support.exp (mi_clean_restart): New.
(mi_run_to_main): Delete.
All callers adjust to use mi_clean_restart / mi_runto_main.
gdb/testsuite/: Use "-qualified" in explicit "break main", etc.
Similar to the previous patch, but this time add "-q" to tests that do
"break main", "list main", etc. explicitly.

gdb/testsuite/: Use -qualified in runto_main / mi_runto_main
In some runtimes, there may be a "main" function in some class or
namespace. The breakpoint created by runto_main may therefore have
unexpected locations on some other functions than the actual main.
These breakpoint locations can unexpectedly get hit during tests and
lead to failures.
I saw this while playing with AMD's ROCm toolchain -- I wrote a board
file to run the testsuite against device kernels. There, the runtime
calls a "main" function before the device kernel code is reached:
Thread 4 "bit_extract" hit Breakpoint 1, 0x00007ffeea140960 in lld::elf::LinkerDriver::main(llvm::ArrayRef<char const*>) () from /opt/rocm/lib/libamd_comgr.so.1

...
To avoid that, pass "qualified" to runto, in runto_main, so that
gdb_breakpoint ends up creating a breakpoint with -qualified. This
avoids creating breakpoints locations for other unrelated "main"
functions.
Note: I first tried making runto itself use "-qualified", but that
caused regressions in the gdb.ada/ tests, which use runto without
specifying the whole fully-qualified function name (i.e., without the
package). So I end up restricting the -qualified to
runto_main/mi_runto_main.
The gdb.base/ui-redirect.exp change is necessary because that testcase
is looking at what "save breakpoint" generates.
gdb/testsuite/ChangeLog:
* gdb.base/ui-redirect.exp: Expect "break -qualified main" in
saved breakpoints file.
* gdb.guile/scm-breakpoint.exp: Expect "-qualified main" when
inspecting breakpoint list.
* lib/gdb.exp (runto_main): Add "qualified" to options.
* lib/mi-support.exp (mi_runto_helper): Add 'qualified' parameter,
and handle it.
(mi_runto_main): Pass 1 as qualified argument.
This adds an mi_runto_main routine, very much like the runto_main CLI
counterpart.
Note there's already a mi_run_to_main (extra underscore in "run_to"),
but unlike its intro comment says, that does more than the CLI's
runto_main -- it also starts GDB. I would like to eliminate that
other one by introducing a mi_clean_restart function instead. That is
done later in the series.
gdb/testsuite/ChangeLog:
* lib/mi-support.exp (mi_runto_main): New proc.
(mi_run_to_main): Use it.

gdb: detect main function even when there's no matching msymbol
Currently, GDB will only stop the backtrace at the main function if
there is a minimal symbol with the matching name. In Fortran programs
compiled with gfortran this is not the case. The main function is
present in the DWARF, and as marked as DW_AT_main_subprogram, but
there's no minimal symbol.
This commit extends `inside_main_func` to check the full symbols if no
matching minimal symbol is found.
There's an updated test case that covers this change.
gdb/ChangeLog:
* frame.c (inside_main_func): Check full symbols as well as
minimal symbols.
gdb/testsuite/ChangeLog:
* gdb.fortran/mixed-lang-stack.exp (run_tests): Update expected
output of backtrace.

ada-lang.c::advance_wild_match improve doc and parameter+temporaries types
This commit fixes the type of one of the parameters as well as a couple
of temporaries.
While at it, the function's description is slightly rewritten to make it
a little clearer what the function does.
gdb/ChangeLog:
* ada-lang.c (advance_wild_match): Rewrite the function's description. Change the type of target0, t0 and t1 to char.
