When preparing the mem events for the argv copies are intentionally made. These copies are leaked and cause runs of perf using address sanitizer to fail. Rather than leak the memory allocate a chunk of memory for the mem event names upfront and build the strings in this - the storage is sized larger than the previous buffer size. The caller is then responsible for clearing up this memory. As part of this change, remove the mem_loads_name and mem_stores_name global buffers then change the perf_pmu__mem_events_name to write to an out argument buffer.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
