This is a very mechanical task that could almost have been done with
sed. Boost versions of mutexes and locks were removed, and replaced with
std:: versions. The replacement tables are as follows:
== Mutexes ==
- boost::mutex -> std::mutex
- boost::recursive_mutex -> std::recursive_mutex
Mutexes behave identically between Boost and std:: and have the same
API.
== Locks ==
C++11 has only two types of lock that we use/need in UHD:
- std::lock_guard: Identical to boost::lock_guard
- std::unique_lock: Identical to boost::unique_lock
Boost also has boost::mutex::scoped_lock, which is a typedef for
boost::unique_lock<>. However, we often have used scoped_lock where we
meant to use lock_guard<>. The name is a bit misleading, "scoped lock"
sounding a bit like an RAII mechanism. Therefore, some previous
boost::mutex::scoped_lock are now std::lock_guard<>.
std::unique_lock is required when doing more than RAII locking (i.e.,
unlocking, relocking, usage with condition variables, etc.).
== Condition Variables ==
Condition variables were out of the scope of this lock/mutex change, but
in UHD, we inconsistently use boost::condition vs.
boost::condition_variable. The former is a templated version of the
latter, and thus works fine with std::mutex'es. Therefore, some
boost::condition_variable where changed to boost::condition.
All locks and mutexes use `#include <mutex>`. The corresponding Boost
includes were removed. In some cases, this exposed issues with implicit
Boost includes elsewhere. The missing explicit includes were added.

The introduction of multi_usrp_rfnoc caused
multi_usrp::get_device()->get_tree() to segfault for gen3 devices.
In defcb174, we introduced a fix for this (multi_usrp::get_tree()) but
we didn't apply it to internal utilities.
That means the uhd_cal_* utilties were broken, along with certain
sections of the C API, and the latency test suite. This fixes the
segfault issue.

Note: template_lvbitx.{cpp,hpp} need to be excluded from the list of
files that clang-format gets applied against.

This adds a separate version of multi_usrp for RFNoC devices. It is
compatible with RFNoC devices only, and prefers C++ APIs over property
tree usage. The factory of multi_usrp is modified such that it picks the
correct version, users of multi_usrp don't care about this change.
This also introduces some API changes:
- Removing redundant GPIO functions. Now all GPIO control, setting, and
readback is done with uint32_t's.
- Adding getter/setter for GPIO source. This was done to simplify the
other GPIO settings, as the source for each pin is not always a
binary. The CTRL mode, for example, can either be ATR or GPIO.
However, the source can be controlled by various radios or "PS" or
some other source.
- Removing the mask from the RFNoC radio controllers' set_gpio_attr().
- Adding state caching to gpio_atr_3000, and a getter for it. Whenever
an attribute is set, that value is cached, and can now be retreieved.
- Remove low-level register API. Since UHD 3.10, there is no USRP that
implements that API.
Modifying the filter API in the following ways:
- Splitting filter API getter/setter/list into separate RX and TX
functions
- Adding channel numbers as an argument
- The filter name will no longer be a property tree path, but rather a
filter name. For RFNoC devices, this will take the form
`BLOCK_ID:FILTER_NAME`. For non-RFNoC devices, this will just be the
filter name (e.g. `HB_1`)
- Removing search mask from listing function. Users can do their own
searching

The Rx LO control was always there, but the Tx LO control was not
exposed into the C API.

The C/C++ standards don't define what time_t is, only that it is
arithmetic (and real for C11, and integral for C++). It should not be
used in portable software and is only used as the return value for some
libc calls.
A common definition for time_t is int64_t, so we'll switch to that
permanently in our own APIs. System APIs will of course stick with
time_t.

In uhd_usrp_get_rx_stream and uhd_usrp_get_tx_stream, an error will now
be propagated into the streamer handle.
|

|

|

uhd_tx_streamer_last_error and uhd_usrp_last_error use
UHD_SAFE_C and so uhd_rx_streamer_last_error should as well
in order to be consistent.
Currently using UHD_SAFE_C_SAVE_ERROR.

Specifically, remove set_tx_dc_offset() and set_tx_iq_balance() calls
that require doubles, and were given bools.

Note: This is the first commit that uses for-range, and range-based
for-loops are now usable for UHD development.
