linux-user/flatload.c: Fix setting of image_info::end_code

The flatload loader sets the end_code field in the image_info struct
incorrectly, due to a typo.

This is a very long-standing bug (dating all the way back to when
the bFLT loader was added in 2006), but has gone unnoticed because
(a) most people don't use bFLT binaries
(b) we don't actually do anything with the end_code field, except
print it in debugging traces and pass it to TCG plugins

Fix the typo.

linux-user: Split linux-user internals out of qemu.h

qemu.h is included in various non-linux-user files (which
mostly want the TaskState struct and the functions for
doing usermode access to guest addresses like lock_user(),
unlock_user(), get_user*(), etc).

Split out the parts that are only used in linux-user itself
into a new user-internals.h. This leaves qemu.h with basically
three things:
* the definition of the TaskState struct
* the user-access functions and macros
* do_brk()
all of which are needed by code outside linux-user that
includes qemu.h.

The addition of all the extra #include lines was done with
sed -i '/include.*qemu\.h/a #include "user-internals.h"' $(git grep -l 'include.*qemu\.h' linux-user)
(and then undoing the change to fpa11.h).

exec: Use cpu_untagged_addr in g2h; split out g2h_untagged

Use g2h_untagged in contexts that have no cpu, e.g. the binary
loaders that operate before the primary cpu is created. As a
colollary, target_mmap and friends must use untagged addresses,
since they are used by the loaders.

Use g2h_untagged on values returned from target_mmap, as the
kernel never applies a tag itself.

Use g2h_untagged on all pc values. The only current user of
tags, aarch64, removes tags from code addresses upon branch,
so "pc" is always untagged.

Use g2h with the cpu context on hand wherever possible.

Use g2h_untagged in lock_user, which will be updated soon.

linux-user: completely re-write init_guest_space

First we ensure all guest space initialisation logic comes through
probe_guest_base once we understand the nature of the binary we are
loading. The convoluted init_guest_space routine is removed and
replaced with a number of pgb_* helpers which are called depending on
what requirements we have when loading the binary.

We first try to do what is requested by the host. Failing that we try
and satisfy the guest requested base address. If all those options
fail we fall back to finding a space in the memory map using our
recently written read_self_maps() helper.

There are some additional complications we try and take into account
when looking for holes in the address space. We try not to go directly
after the system brk() space so there is space for a little growth. We
also don't want to have to use negative offsets which would result in
slightly less efficient code on x86 when it's unable to use the
segment offset register.

Less mind-binding gotos and hopefully clearer logic throughout.

linux-user/flatload.c: Use "" for include of QEMU header target_flat.h

The target_flat.h file is a QEMU header, so we should include it using

linux-user/flatload.c: Use "" for include of QEMU header target_flat.h

The target_flat.h file is a QEMU header, so we should include it using
quotes, not angle brackets.

Coverity otherwise is unable to find the header:

"../linux-user/flatload.c", line 40: error #1712: cannot open source file
"target_flat.h"
#include <target_flat.h>
^

because the relevant directory is only on the -iquote path, not the -I path.
