f6c0f35e07 Keep shadow copies of the e_shnum', e_phnum' and `e_shstrndx' 
members of the ELF Executable Header inside the library-private
`struct _Elf' descriptor and only update the underlying Elf{32,64}_Ehdr
structure on an elf_update(3) call.  These fields of the Ehdr
structure are technically `out of bounds' for an application program
per the ELF(3) API, but we've seen applications that initialize
a new Ehdr structure using memcpy(), messing up the library's
invariants. [1]

Implement elf_getphnum() and handle ELF objects with more than
64K program header table entries.

a2dc08f2b8 Use strncpy() instead of strlcpy() when copying members of 
a `struct ar_hdr'.  These members do not use NUL-termination
while strlcpy() expects its source buffer to be NUL-terminated.

63067c1af8 Fix a typo in __fpu_ftox() that caused long double to long (and long long) 
conversion of negative numbers to always result in -1.
While at it, rearrange the nearby comment so it fits in 80 chars per line,
like the rest of this file does.

ee0ab7cd86 Implement chunk allocation/deallocation hysteresis by caching one spare 
chunk per arena, rather than immediately deallocating all unused chunks.
This fixes a potential performance issue when allocating/deallocating

977e36e94a Clean bound and non-bound pthread structures consistently before 
they become candidates for reuse.  Without this fix, some of the
state from a thread structure's previous incarnation could interfere
with its new one. Specifically, a non-bound thread started as
"suspended" (see pthread_attr_setcreatesuspend_np()) might not get
scheduled at all when resumed, as the "active" flag would be set
spuriously.

2dacb27e06 Use <osreldate.h> rather than the OS version reported by the kernel 
to determine which Elf Types are to be handled.  Change the M4
templates to wrap an `#if __FreeBSD_version >= NNN'/`#endif' pair
around the generated code for each ELF data type, where `NNN' is
the OS version where the ELF type was added to the source tree.

This change allows cross-builds of old sources on newer FreeBSD
systems to work correctly.
