a0e4fe2340 Fixed double free() in level1v example (#482)
Details:
- In exampls/tapi/00level1v.c, pointer 'z' was being freed twice and
  pointer 'a' was not being freed at all. This commit correctly frees 
  each pointer exactly once.

882dcb11bf Mention example code at top of documentation docs.
Details:
- Steer the reader towards the example code section of each
  documentation doc (object and typed).
- Trivial update to examples/oapi/README, examples/tapi/README.

057f5f3d21 Minor build system housekeeping.
Details:
- Commented out redundant setting of LIBBLIS_LINK within all driver-
  level Makefiles. This variable is already set within common.mk, and
  so the only time it should be overridden is if the user wants to link
  to a different copy of libblis.
- Very minor changes to build/gen-make-frags/gen-make-frag.sh.
- Whitespace and inconsequential quoting change to configure.
- Moved top-level 'windows' directory into a new 'attic' directory.

0645f239fb Remove UT-Austin from copyright headers' clause 3.
Details:
- Removed explicit reference to The University of Texas at Austin in the
  third clause of the license comment blocks of all relevant files and
  replaced it with a more all-encompassing "copyright holder(s)".
- Removed duplicate words ("derived") from a few kernels' license
  comment blocks.
- Homogenized license comment block in kernels/zen/3/bli_gemm_small.c
  with format of all other comment blocks.

bb6df2814f Defined a new level-1d operation: shiftd.
Details:
- Defined a new level-1d operation called 'shiftd', including object and
  typed APIs. This operation adds a scalar value to every element along
  an arbitrary diagonal of a matrix. Currently, shiftd is implemented in
  terms of the addv kernel. (The scalar is passed in as the x vector
  with an increment of zero.)
- Replaced ad-hoc usage of setd and addd (after creating a temporary
  matrix object) with use of shiftd, which is much more concise, in
  various test driver files in the testsuite. Similar changes were made
  to the standalone test drivers and the example code.
- Added documentation entries in BLISObjectAPI.md and BLISTypedAPI.md
  for bli_shiftd() and bli_?shiftd(), respectively.
- Added observed object properties to level-1d documentation in
  BLISObjectAPI.md.

4b5437ec7a Define a cpp macro specific to BLIS compilation.
Details:
- Tweaked the cflags functions in common.mk so that a new preprocessor
  macro, BLIS_IS_BUILDING_LIBRARY, is defined, but only when BLIS
  itself is being built. This macro will not be defined when, for
  example, the testsuite or example code compiles code local to those
  applications. This was done in part by defining a new cflags function
  get-user-cflags-for(), which is now the designated function for
  application Makefiles if they wish to inherit a basic set of CFLAGS
  from BLIS. (The compiler flags returned are identical to that of
  get-frame-cflags-for() except that -DBLIS_IS_BUILDING_LIBRARY is
  omitted.)
- Updated all test driver-like makefiles to call get-user-cflags-for()
  instead of get-frame-cflags-for().

4fa4cb0734 Trivial comment header updates.
Details:
- Removed four trailing spaces after "BLIS" that occurs in most files'
  commented-out license headers.
- Added UT copyright lines to some files. (These files previously had
  only AMD copyright lines but were contributed to by both UT and AMD.)
- In some files' copyright lines, expanded 'The University of Texas' to
  'The University of Texas at Austin'.
- Fixed various typos/misspellings in some license headers.

0f491e994a Allow lesser Makefiles to reference installed BLIS.
Details:
- Updated the build system so that "lesser" Makefiles, such as those in
  belonging to example code or the testsuite, may be run even if the
  directory is orphaned from the original build tree. This allows a
  user to configure, compile, and install BLIS, delete the build tree
  (that is, the source distribution, or the build directory for out-
  of-tree builds) and then compile example or testsuite code and link
  against the installed copy of BLIS (provided the example or testsuite
  directory was preserved or obtained from another source). The only
  requirement is that make be invoked while setting the
  BLIS_INSTALL_PATH variable to the same installation prefix used when
  BLIS was configured. The easiest syntax is:

    make BLIS_INSTALL_PATH=/install/prefix

  though it's also permissible to set BLIS_INSTALL_PATH as an
  environment variable prior to running 'make'.
- Updated all lesser Makefiles to implement the new aforementioned build
  behavior.
- Relocated check-blastest.sh and check-blistest.sh from build to
  blastest and testsuite, respectively, so that if those directories are
  copied elsewhere the user can still run 'make check' locally.
- Updated docs/Testsuite.md with language that mentions this new option
  of building/linking against an installed copy of BLIS.

e88aedae73 Separated expert, non-expert typed APIs.
Details:
- Split existing typed APIs into two subsets of interfaces: one for use
  with expert parameters, such as the cntx_t*, and one without. This
  separation was already in place for the object APIs, and after this
  commit the typed and object APIs will have similar expert and non-
  expert APIs. The expert functions will be suffixed with "_ex" just as
  is the case for expert interfaces in the object APIs.
- Updated internal invocations of typed APIs (functions such as
  bli_?setm() and bli_?scalv()) throughout BLIS to reflect use of the
  new explictly expert APIs.
- Updated example code in examples/tapi to reflect the existence (and
  usage) of non-expert APIs.
- Bumped the major soname version number in 'so_version'. While code
  compiled against a previous version/commit will likely still work
  (since the old typed function symbol names still exist in the new API,
  just with one less function argument) the semantics of the function
  have changed if the cntx_t* parameter the application passes in is
  non-NULL. For example, calling bli_daxpyv() with a non-NULL context
  does not behave the same way now as it did before; before, the
  context would be used in the computation, and now the context would
  be ignored since the interace for that function no longer expects a
  context argument.

b45ea92fc6 Added typed (BLAS-like) API code examples.
Details:
- Added new example code to examples/tapi demonstrating how to use the
  BLIS typed API. These code examples directly mirror the corresponding
  example code files in examples/oapi. This setup provides a convenient
  opportunity for newcomers to BLIS to compare and contrast the typed
  and object APIs when they are used to perform the same tasks.
- Minor cleanups to examples/oapi.
