2010-09-01[gdbserver] Move malloc.h include to server.h.gdbadmin1-3/+0
This patch moves all includes of malloc.h, which were introduced purely to get access to alloca's declaration, to server.h, next to the include of alloca.h. There is one exception: gdbreplay.c, which does not include server.h. In this case, the include of alloca.h was simply moved up a bit, next to the include of malloc.h. gdb/gdbserver/ChangeLog: * gdbreplay.c: Move include of alloca.h up, next to include of malloc.h. * server.h: Add include of malloc.h. * mem-break.c: Remove include of malloc.h. * server.c, tracepoint.c, utils.c, win32-low.c: Likewise.

snprintf is not available on LynxOS, so I changed the calls to snprintf to calls to xsnprintf, which should be strictly equivalent. gdb/gdbserver/ChangeLog: * utils.c (xsnprintf): Make non-static. * server.h: Add xsnprintf declaration. * linux-low.c, nto-low.c, target.c, thread-db.c, tracepoint.c: replace calls to snprintf by calls to xsnprintf throughout.
