system/cpus: rename qemu_mutex_lock_iothread() to bql_lock()

The Big QEMU Lock (BQL) has many names and they are confusing. The
actual QemuMutex variable is called qemu_global_mutex but it's commonly
referred to as the BQL in discussions and some code comments. The
locking APIs, however, are called qemu_mutex_lock_iothread() and
qemu_mutex_unlock_iothread().

The "iothread" name is historic and comes from when the main thread was
split into into KVM vcpu threads and the "iothread" (now called the main
loop thread). I have contributed to the confusion myself by introducing
a separate --object iothread, a separate concept unrelated to the BQL.

The "iothread" name is no longer appropriate for the BQL. Rename the
locking APIs to:
- void bql_lock(void)
- void bql_unlock(void)
- bool bql_locked(void)

There are more APIs with "iothread" in their names. Subsequent patches
will rename them. There are also comments and documentation that will be
updated in later patches.

dump_init() first computes the size of the dump, taking the filter

This is redundant: if the size of the dump is zero, there is no

dump: Recognize "fd:" protocols on Windows hosts

A few QMP command can work with named file descriptors.

The only way to create a named file descriptor used to be QMP command
getfd, which only works on POSIX hosts. Thus, named file descriptors
were actually usable only there.

They became usable on Windows hosts when we added QMP command
get-win32-socket (commit 4cda177c601 "qmp: add 'get-win32-socket'").

Except in dump-guest-memory, because qmp_dump_guest_memory() compiles
its named file descriptor code only #if !defined(WIN32).

Compile it unconditionally, like we do for the other commands
supporting them.

dump: Add command interface for kdump-raw formats

The QMP dump API represents the dump format as an enumeration. Add three
new enumerators, one for each supported kdump compression, each named
"kdump-raw-*".

For the HMP command line, rather than adding a new flag corresponding to
each format, it seems more human-friendly to add a single flag "-R" to
switch the kdump formats to "raw" mode. The choice of "-R" also
correlates nicely to the "makedumpfile -R" option, which would serve to
reassemble a flattened vmcore.

dump: Allow directly outputting raw kdump format

The flattened format (currently output by QEMU) is used by makedumpfile
only when it is outputting a vmcore to a file which is not seekable. The
flattened format functions essentially as a set of instructions of the
form "seek to the given offset, then write the given bytes out".

The flattened format can be reconstructed using makedumpfile -R, or
makedumpfile-R.pl, but it is a slow process because it requires copying
the entire vmcore. The flattened format can also be directly read by
crash, but still, it requires a lengthy reassembly phase.

To sum up, the flattened format is not an ideal one: it should only be
used on files which are actually not seekable. This is the exact
strategy which makedumpfile uses, as seen in the implementation of
"write_buffer()" in makedumpfile [1]. However, QEMU has always used the
flattened format. For compatibility it is best not to change the default
output format without warning. So, add a flag to DumpState which changes
the output to use the normal (i.e. raw) format. This flag will be added
to the QMP and HMP commands in the next change.

migration: simplify blockers

Modify migrate_add_blocker and migrate_del_blocker to take an Error **
reason. This allows migration to own the Error object, so that if
an error occurs in migrate_add_blocker, migration code can free the Error
and clear the client handle, simplifying client code. It also simplifies
the migrate_del_blocker call site.

In addition, this is a pre-requisite for a proposed future patch that would
add a mode argument to migration requests to support live update, and
maintain a list of blockers for each mode. A blocker may apply to a single
mode or to multiple modes, and passing Error** will allow one Error object
to be registered for multiple modes.

No functional change.

dump: kdump-zlib data pages not dumped with pvtime/aarch64

The kdump-zlib data pages are not dumped from aarch64 host when the
'pvtime' is involved, that is, when the block->target_end is not aligned to
page_size. In the below example, it is expected to dump two blocks.

(qemu) info mtree -f
... ...
00000000090a0000-00000000090a0fff (prio 0, ram): pvtime KVM
... ...
0000000040000000-00000001bfffffff (prio 0, ram): mach-virt.ram KVM
... ...

However, there is an issue with get_next_page() so that the pages for
"mach-virt.ram" will not be dumped.

At line 1296, although we have reached at the end of the 'pvtime' block,
since it is not aligned to the page_size (e.g., 0x10000), it will not break
at line 1298.

1255 static bool get_next_page(GuestPhysBlock **blockptr, uint64_t *pfnptr,
1256 uint8_t **bufptr, DumpState *s)
... ...
1294 memcpy(buf + addr % page_size, hbuf, n);
1295 addr += n;
1296 if (addr % page_size == 0) {
1297 /* we filled up the page */
1298 break;
1299 }

As a result, get_next_page() will continue to the next
block ("mach-virt.ram"). Finally, when get_next_page() returns to the
caller:

- 'pfnptr' is referring to the 'pvtime'
- but 'blockptr' is referring to the "mach-virt.ram"

When get_next_page() is called the next time, "*pfnptr += 1" still refers
to the prior 'pvtime'. It will exit immediately because it is out of the
range of the current "mach-virt.ram".

The fix is to break when it is time to come to the next block, so that both
'pfnptr' and 'blockptr' refer to the same block.
