This patch aims to introduce a change in enabling
tracepoints inside SPDK. Currently every hit tracepoint will
be stored inside an internal buffer, what is inconvenient when
looking for certain information (eg. starting IO to record
some tracepoints, stopping the IO and having the tracepoint
buffer flooded with irrelevant information before copying the
contents connected with IO operations).
The tpoint mask option (-e) has been extended with ':' character.
User may now enter tpoint mask for individual trace points
inside chosen tpoint group.
Example: "-e 0x20:3f", where "0x20" stands for tpoint group,
':' is a separator and "3f" is the tpoint mask.

Currently we do not have any way to connect traces from different
modules in SPDK. This change modifies our trace library
and app/trace to handle adding relations between trace points
and a trace object.
Additionally this patch adds classes and fields to structs
inside trace.py to prepare it for future patches implementing
printing relation information.

This patch adds the ability to chain multiple trace entries together to
extend the size of the argument buffer. This means that a tracepoint is
no longer limited to the size of a single entry, so it can have any
number of arguments, and their size is also not constrained to a single
entry.
Some limitations are still there: a tracepoint can have up to 5
arguments and strings are limited to 255 bytes. These constraints stem
from the definitions of tracepoint structures, which could be easily
modified to extend the limits if needed.
To record a tracepoint requiring larger buffer, aside from reserving
`spdk_trace_entry` structure, a series of `spdk_trace_entry_buffer`
structures are allocated too. Each of them acts as a buffer for the
arguments. To allow trace tools to treat the buffer structures
similarly to regular entries, they also have the `tpoint_id` and `tsc`
fields. The id is always assigned to `SPDK_TRACE_MAX_TPOINT_ID` to make
sure that a buffer is never mistaken for an entry, while the value of
`tsc` is always shared with the initial entry. This also provides a way
for the trace tools to verify if an entry is part of a chained buffer.

Now that each tracepoint can have more than one argument, we cannot pad
the missing ones, as it would take too much space. Therefore, we put
them at the end of a line and simply skip the missing ones.
Additionally, since empty arguments are no longer padded, this patch
stops recording arguments with names consisting of an empty string
(containing just '\0').

Now that `spdk_trace_record` receives variadic arguments, we no longer
have to pass strings as uint64_t, but can pass them directly as
pointers. That also means that the recorded strings can be longer than
8B (up to 40B).
This patch changes the blobfs code to pass the filenames as strings and
gets rid of the code that converted them to uint64_t.
Additionally, the maximum length of string arguments printed by
`app/trace/trace` has been extended to 16 and they're also padded to 16
characters, to better align with other argument types.

This patch allows tracepoint to record a variable number of arugments.
An additional function has been added,
`spdk_trace_register_description_ext()`, which allows the user to
register definitions for tracepoints specifying all the arugments that
they accept. Users can also call `spdk_trace_register_description()` to
register tpoints with a single argument (or none).
Currently, all of the tracepoint arguments need to be passed as
uint64_t.
The trace record functions use variable arguments and rely on tracepoint
description to know the order and the format of the arguments passed.
That means that the user needs to take care that they're always in sync.
Moreover, this patch extends the tracepoint entry size from 32B to 64B,
meaning that there are 40B that can be utilized for passing arguments,
which in turn means that there can be up to 5 arguments per tracepoint.
