glibc/malloc
History
Joseph Myers c923cd8c49 Avoid use of atoi in malloc 
This patch is analogous to commit
a3708cf6b0.

atoi has undefined behavior on out-of-range input, which makes it
problematic to use anywhere in glibc that might be processing input
out-of-range for atoi but not specified to produce undefined behavior
for the function calling atoi.  In conjunction with the C2x strtol
changes, use of atoi in libc can also result in localplt test failures
because the redirection for strtol does not interact properly with the
libc_hidden_proto call for __isoc23_strtol for the call in the inline
atoi implementation.

In malloc/arena.c, this issue shows up for atoi calls that are only
compiled for --disable-tunables (thus with the
x86_64-linux-gnu-minimal configuration of build-many-glibcs.py, for
example).  Change those atoi calls to use strtol directly, as in the
previous such changes.

Tested for x86_64 (--disable-tunables).
