Call poll at a fixed interval.

The existing implementation blocks in select() for a fixed amount of
time. This change tracks when the next event (likely poll()) wants to be
run, and uses a shorter timeout in select() if necessary.

Also track all these timeouts using milliseconds as returned by
timeval_ms() instead of `struct timeval` to simplify the code.

This feature is helpful if poll() wants to do something like sample PCs
or memory values for basically the entire time that otherwise OpenOCD
would be hung in select(). See
https://github.com/riscv/riscv-openocd/pull/541 for an example of that.
The RISC-V code using this change will be upstreamed some day, too.

jtag/aice: fix build with clang on MacOS

Commit fceb29d03ff9 ("jtag/aice: use macros in place of const
variables") replaces some 'static const uint8_t' with macros.
This breaks the build on MacOS because the macro values are of
'int' type that doesn't match with the printf format 'PRIx8'.

error: format specifies type 'unsigned char' but the
argument has type 'int' [-Werror,-Wformat]

Replace the printf format 'PRIx8' with 'x'.
While there, remove a useless cast to uint32_t and fix the printf
format too.

stlink: fix SIGSEGV with libusb v1.0.24-33-g32a2206 (11618)

The stlink driver incorrectly uses a NULL pointer for libusb's
struct libusb_context.
The correct value to be used is local in libusb_helper.c.

Move in the helper file, in a wrapper function, the only call that
requires the above value, and let stlink driver to use this
wrapper.

This issue has not triggered any visible problem until a code
refactoring [1] in libusb has made OpenOCD crashing on Windows and
on MacOS.

the default target using the 'targets' command. This way, the
user can start debugging code running on the boot core without
having to switch to the boot core by explicitly invoking 'targets'
command first, since it is likely the debugged code will run on
the boot core. Note that most of the code is already in place, it
was just not used, so this is more of a fix to make the original
intention work.

server/telnet: fix autocomplete for jimtcl commands

Current autocomplete filters-out some command reported by "info
commands". One of the filter rule concerns the command's private
data.
Every command registered by OpenOCD has its 'struct command' as
private data.

By ignoring commands without private data, we loose several TCL
commands registered by jimtcl, e.g. 'foreach', 'llength'.

By assuming that every command with non-NULL private data has
'struct command' as private data, we risk at best to access
inconsistent data, at worst to trigger a segmentation fault.

Export the already available functions:
- to check if a command has been registered by OpenOCD and
- to get the private data.
While there, rename jimcmd_is_ocd_command() as
jimcmd_is_oocd_command().
Don't filter-out jimtcl commands with no private data.
Check the private data only on OpenOCD commands.

helper/jim-nvp: comply with coding style [1/2]

The helper jim-nvp does not comply with OpenOCD coding style due
to typedef of struct and CamelCase symbol names.
While it's trivial fixing the helper and all its current use in
the code, changing these APIs will potentially break a number of
patches pending in gerrit. Gerrit will not trigger any alert, but
the code will generate compile error after the merge.

Add the compile flag "-Wno-error=deprecated-declarations" to keep
as warning (not as error) the use of "deprecated" functions and
types.
Rename all the CamelCase symbols is lowercase and provide struct
prototypes in place of the typedef.
Add a DEPRECATED section to 'jim-nvp.h' where the old CamelCase
symbols and the old typedef are re-declared with compile attribute
'deprecated'.

With this change OpenOCD compiles, but generates warnings.
The remaining changes allover OpenOCD code will be fixed in a
separate patch for easier review.

The patches merged later that still use the old deprecated API
will compile with warnings. This will permit to identify and fix
these cases.

target/cortex_a: add support for watchpoints

The current implementation of OpenOCD does not support watchpoints for
cortex_a architecture. So, I replaced the add_watchpoint and
remove_watchpoint with the specific implementation for the
cortex a and using the breakpoint implementation and the arm
documentation [1] as reference. In particular, I have made the
following changes:

* added the following functions

- cortex_a_add_watchpoint
  This wrapper function check whether there are any watchpoint
  available on the target device by calling cortex_a_set_watchpoint.

- cortex_a_set_watchpoint
  This function is responsible for settings the watchpoint register
  pair. In particular, it sets the WVR and the WCR registers with
  the cortex_a_dap command.

- cortex_a_remove_watchpoint
  This wrapper function the selected watchpoint on the target device
  by calling cortex_a_unset_watchpoint.

- cortex_a_unset_watchpoint
  This function sets both the WVR and the WCR registers to zero, thus
  unsetting the watchpoint.

When a WAIT occurs the commands after the WAIT are replayed and the
STICKYORUN is cleared. However if another WAIT occurs during the
command replay, the command itself is resent but the STICKYORUN bit
shall also be cleared. If this is not done, the MEM-AP hangs.
