c1a18fb514 bluetooth: host: Specify controller in BT_HCI_TX_STACK_SIZE defaults
By specifying the controller directly when selecting the default
BT_HCI_TX_STACK_SIZE, an external controller may rely on the final
default value when none of the in-tree controllers are used.

The value is increased to 1024 to accomodate the current worst-case
stack size.

4344e27c26 all: Update reserved function names
Update reserved function names starting with one underscore, replacing
them as follows:
   '_k_' with 'z_'
   '_K_' with 'Z_'
   '_handler_' with 'z_handl_'
   '_Cstart' with 'z_cstart'
   '_Swap' with 'z_swap'

This renaming is done on both global and those static function names
in kernel/include and include/. Other static function names in kernel/
are renamed by removing the leading underscore. Other function names
not starting with any prefix listed above are renamed starting with
a 'z_' or 'Z_' prefix.

Function names starting with two or three leading underscores are not
automatcally renamed since these names will collide with the variants
with two or three leading underscores.

Various generator scripts have also been updated as well as perf,
linker and usb files. These are
   drivers/serial/uart_handlers.c
   include/linker/kobject-text.ld
   kernel/include/syscall_handler.h
   scripts/gen_kobject_list.py
   scripts/gen_syscall_header.py

b34b2c5a94 Bluetooth: kconfig: Remove redundant dependencies
subsys/bluetooth/common/Kconfig and subsys/bluetooth/host/Kconfig are
'source'd within 'if BT' and 'if BT_HCI', in subsys/bluetooth/Kconfig,
so there's no need to add those dependencies within them.

'if FOO' is just shorthand for adding 'depends on FOO' to each item
within the 'if'. Dependencies on menus work similarly. There are no
"conditional includes" in Kconfig, so 'if FOO' has no special meaning
around a source. Conditional includes wouldn't be possible, because an
if condition could include (directly or indirectly) forward references
to symbols not defined yet.

Tip: When adding a symbol, check its dependencies in the menuconfig
('ninja menuconfig', then / to jump to the symbol). The menuconfig also
shows how the file with the symbol got included, so if you see
duplicated dependencies, it's easy to hunt down where they come from.

da163794d0 Bluetooth: GATT: Add BT_GATT_CCC_MANAGED
This adds another helper macro called BT_GATT_CCC_MANAGED which can be
used to set 2 new callbacks:

 - cfg_write: Which application can set if it wants to manage writes to
 CCC configuration.
 - cfg_match: Which application can set if it wants to manage matching
 CCC configuration when notifying/indicating.

BT_GATT_CCC_MANAGED retains the ability of saving peer configuration
on storage making it useful for clients which are only interrested in
managing the CCC configuration but not the storage itself.

75f77db432 include: misc: util.h: Rename min/max to MIN/MAX
There are issues using lowercase min and max macros when compiling a C++
application with a third-party toolchain such as GNU ARM Embedded when
using some STL headers i.e. <chrono>.

This is because there are actual C++ functions called min and max
defined in some of the STL headers and these macros interfere with them.
By changing the macros to UPPERCASE, which is consistent with almost all
other pre-processor macros this naming conflict is avoided.

All files that use these macros have been updated.
