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.

70640a3710 Implemented library self-initialization.
Details:
- Defined two new functions in bli_init.c: bli_init_once() and
  bli_finalize_once(). Each is implemented with pthread_once(), which
  guarantees that, among the threads that pass in the same pthread_once_t
  data structure, exactly one thread will execute a user-defined function.
  (Thus, there is now a runtime dependency against libpthread even when
  multithreading is not enabled at configure-time.)
- Added calls to bli_init_once() to top-level user APIs for all
  computational operations as well as many other functions in BLIS to
  all but guarantee that BLIS will self-initialize through the normal
  use of its functions.
- Rewrote and simplified bli_init() and bli_finalize() and related
  functions.
- Added -lpthread to LDFLAGS in common.mk.
- Modified the bli_init_auto()/_finalize_auto() functions used by the
  BLAS compatibility layer to take and return no arguments. (The
  previous API that tracked whether BLIS was initialized, and then
  only finalized if it was initialized in the same function, was too
  cute by half and borderline useless because by default BLIS stays
  initialized when auto-initialized via the compatibility layer.)
- Removed static variables that track initialization of the sub-APIs in
  bli_const.c, bli_error.c, bli_init.c, bli_memsys.c, bli_thread, and
  bli_ind.c. We don't need to track initialization at the sub-API level,
  especially now that BLIS can self-initialize.
- Added a critical section around the changing of the error checking
  level in bli_error.c.
- Deprecated bli_ind_oper_has_avail() as well as all functions
  bli_<opname>_ind_get_avail(), where <opname> is a level-3 operation
  name. These functions had no use cases within BLIS and likely none
  outside of BLIS.
- Commented out calls to bli_init() and bli_finalize() in testsuite's
  main() function, and likewise for standalone test drivers in 'test'
  directory, so that self-initialization is exercised by default.

5f93cbe870 Introduced API-level initialization.
Details:
- Added API-level initialization state to _const, _error, _mem, _thread,
  _ind, and _cntl APIs. While this functionality will mostly go unused,
  adding miniscule overhead at init-time, there will be at least once
  instance in the near future where, in order to avoid an infinite loop,
  a certain portion of the initialization will call a query function that
  itself attempts to call bli_init(). API-level initialization will allow
  this later stage to verify that an earlier stage of initialization has
  completed, even if the overall call to bli_init() has not yet returned.
- Added _is_initialized() functions for each API, setting the underlying
  bool_t during _init() and unsetting it during _finalize().
- Comment, whitespace changes.

b6ee82a3d4 Minor cleanup to bli_init() and friends.
Details:
- Spun-off initialization of global scalar constants to bli_const_init()
  and of threading stuff to bli_thread_init().
- Added some missing _finalize() functions, even when there is nothing
  to do.

5c2c6c8561 Updated copyright headers to contain "at Austin".
Details:
- Updated copyright headers to include "at Austin" in the name of the
  University of Texas.
- Updated the copyright years of a few headers to 2014 (from 2011 and
  2012).

4b7e7970f1 Migrated integer usage to stdint.h types.
Details:
- Changed the way bli_type_defs.h defines integer types so that dim_t,
  inc_t, doff_t, etc. are all defined in terms of gint_t (general signed
  integer) or guint_t (general unsigned integer).
- Renamed Fortran types fchar and fint to f77_char and f77_int.
- Define f77_int as int64_t if a new configuration variable,
  BLIS_ENABLE_BLIS2BLAS_INT64, is defined, and int32_t otherwise.
  These types are defined in stdint.h, which is now included in blis.h.
- Renamed "complex" type in f2c files to "singlecomplex" and typedef'ed
  in terms of scomplex.
- Renamed "char" type in f2c files to "character" and typedef'ed in terms
  of char.
- Updated bla_amax() wrappers so that the return type is defined directly
  as f77_int, rather than letting the prototype-generating macro decide
  the type. This was the only use of GENTFUNC2I/GENTPROT2I-related macros,
  so I removed them. Also, changed the body of the wrapper so that a
  gint_t is passed into abmaxv, which is THEN typecast to an f77_int
  before returning the value.
- Updated f2c code that accessed .r and .i fields of complex and
  doublecomplex types so that they use .real and .imag instead (now that
  we are using scomplex and dcomplex).

b65cdc57d9 Migrated 'bl2' prefix to 'bli'.
Details:
- Changed all filename and function prefixes from 'bl2' to 'bli'.
- Changed the "blis2.h" header filename to "blis.h" and changed all
  corresponding #include statements accordingly.
- Fixed incorrect association for Fran in CREDITS file.
