Problem: If the same memory location is accessed alternatively
by MEM-AP banked data registers without autoincrement and by standard
autoincremented read/write, TAR register is not updated correctly.
How to replicate: On a Cortex-M issue
mdw 0xe000edf0
multiple times. When poll is on (poll reads the same memory location)
only the first read is correct.
0xe000edf0: 01000000
0xe000edf0: 00000000
0xe000edf0: 20002640
0xe000edf0: 01000000
0xe000edf0: 00000000
0xe000edf0: 00000000
No problems with poll off.
0xe000edf0: 01000000
0xe000edf0: 01000000
0xe000edf0: 01000000
mem_ap_setup_tar() writes to MEM_AP_REG_TAR if requested TAR value
changed or CSW_ADDRINC_... is currently active.
However if an autoincremented access has been issued and autoinc
switched off in CSW afterwards, TAR does not get updated.
The change introduces mem_ap_update_tar_cache() which is called
after queuing of any access to MEM_AP_REG_DRW. It simulates
TAR increment to keep tar_value in sync with MEM_AP.
Crossing tar autoincrement block boundary invalidates cached value.
mem_ap_write() and mem_ap_read() do not check tar autoincrement
block boundary, mem_ap_setup_tar() is called before each transfer instead.
dap_invalidate_cache() is introduced to ensure invalidation
of all cached values during dap_dp_init() and swd_connect()

The existing code only used Memory Access mode to read memory,
which uses 32 bit operations only.
Rework the code to check the alignment/size of the read/write operation,
and use the Memory Access mode to read aligned 32 bit memory.
When using unaligned access, or 8 or 16 bit reads, use LDR{BHW} and STR{BHW}
instead.
The exception handling is still the same as it was before (meaning it breaks
when things go wrong), but I can now read an 8 bit register correctly.

Commit ef02b69b14 included

cmsis_dap_cmd_DAP_SWJ_Sequence(). According to comment
it is necessary for at least Keil ULINK-ME.
Commit 72c3464be4 added
a cmsis_dap_cmd_DAP_Disconnect() before connect call to pair
connection/disconnection. It solves some problems on Atmel EDBG.
Unfortunately calling either of cmsis_dap_cmd_DAP_Connect()
or cmsis_dap_cmd_DAP_Disconnect() deasserts reset signal.
So these workarounds break ability to connect under reset.
Use cmsis_dap_cmd_DAP_Disconnect() and cmsis_dap_cmd_DAP_Connect()
pair only if both SRST and TRST are deasserted.

In cortex_m_assert_reset, in two locations, DHCSR is written directly
using mem_ap_write_u32. This means that the cached version,
target_to_cm(target)->dcb_dhcsr, is not updated when these writes are
performed, so subsequent writes to DHCSR that use
cortex_m_write_debug_halt_mask will change those bits back to their old
values which, unless modified in that particular invocation, come from
the cache. This causes an actual, observable bug on an STM32F7 in which
running “reset run” immediately after “program” can in some cases result
in execution proceeding with C_MASKINTS set (it is cleared on line 1021
but is then set immediately afterward in cortex_m_clear_halt), causing
failure of the application. Replace these mem_ap_write_u32 calls with
cortex_m_write_debug_halt_mask calls to do the same jobs.
