73cc72729a
This patch moves the gdb/gnulib subdirectory to the top level. It adjusts the top-level build system to build gnulib when necessary, and changes gdb to use this. However, gdbserver still builds its own copy of gnulib, just from the new source location. A small hack was needed to ensure that gnulib is only built when gdb is enabled. The Makefile only provides an ordering -- the directory must be mentioned in configdirs to actually be compiled at all. Most of the patch is just a "git mv" of gnulib, though a few minor path adjustments were needed in some files there. Tested by the buildbot.

/* alloca (N) returns a pointer to N bytes of memory

allocated on the stack, which will last until the function returns.
|
|
Use of alloca should be avoided:
|
|
- inside arguments of function calls - undefined behaviour,
|
|
- in inline functions - the allocation may actually last until the
|
|
calling function returns,
|
|
- for huge N (say, N >= 65536) - you never know how large (or small)
|
|
the stack is, and when the stack cannot fulfill the memory allocation
|
|
request, the program just crashes.
